Vernal ponds are the coral reefs of the forest… critical, disconnected, temporary and unfortunately unprotected habitats that provide vital habitat for unique fauna that fully depend on them!. Because of their temporary, isolated nature, fish cannot live in these wetlands, allowing them to provide safe havens for obligate species such as salamanders, fairy shrimp, endangered turtles, and wood frogs to eat, breed, and flourish. Walking into a forest or oak savannah on a moist, warm, low wind night, makes this abundance clear, the vibration of frog calls clearly delineating these keystone, spring wildlife hotspots. The bugs that proliferate in these vernal ponds form an insect buffet for songbirds, bats, and frogs. Mammals benefit from access to water. Beyond animal life, they capture run off, sink water, clean water, prevent flooding, and breakdown forest litter helping cycle nutrients. As important as they are, vernal ponds are not protected by law because of their ephemeral nature; small, often less than 1 acre, temporary, dry by summer, and isolated from other bodies of water.. they fall short of definitions of wetlands for state and federal protection. In one of the less notorious, yet on-going devastating acts of Trump’s first administration, he gutted the Clean Water Act by narrowing the definition of "Waters of the United States,” reducing protections to wetlands to those that maintain regular surface water connection to a "relatively permanent" body of water, such as a river or lake. Federal protections have been weakened. While Michigan is one of the few states with its own authority to manage wetlands habitat (act 451 Part 303), the state mostly regulates wetlands larger than 5 acres. For smaller wetlands to be protected, they must be “contiguous" to a Great Lake, inland lake, pond, river, or stream. This usually means being within 500 feet of an inland water body or 1,000 feet of a Great Lake. Part 303 does protect “rare and imperiled" wetland types, but vernal pools are not currently explicitly listed under this category. They should be! A flood of development, from weakening federal protections, and lack of state support threaten our unprotected vernal ponds. But one network has been mapping and documenting vernal ponds, gathering data that could be used to save them in the future: the Michigan Vernal Pools Partnership (MVPP) by Michigan Natural Features Inventory. Both of our staff here at Rouge Park, Noor and Antonio, have been trained under the MVPP, as well as Sally before us. We are monitoring these ponds in Rouge Park and building out ways for more youth and the general public to participate in that. Our Vernal Ponds are safe from development, not even Trump can touch them, but they face another threat: CSO-flood waters. As I have covered in previous articles, the Rouge Watershed is 80% developed, there are so few wetlands that our park floods very regularly.. That floodwater far too often includes human waste water because of the Combined Sewer Overflow systems that combine rain water from roofs and streets with toilet waste water underground, which is fine so long as you don’t have heavy downpours regularly.. as we do these days. These flood waters can introduce untreated sewage, negative pathogens, nutrients and toxins. This can plummet water oxygen levels, introduce invasive species, even fish that disrupt habitat, making the place unsuitable for more sensitive amphibians. Ultimately this reduces the quality of the pond! But nature persists. In fact we had to cancel our Vernal Pond exploration activity on April 18th because of this exact reason. Luckily in the days prior, we hosted St Suzanne’s youth checking at the vernal pond north of Tireman and Spinoza. We did find fairy shrimp which was super cool! Most importantly, local youth got a chance to use microscopes and dig into some citizen science. I noticed the prior week’s rains flooded the river, which began flowing into the pond. Hopefully flood waters didn’t negatively impact those fairy shrimp! Luckily we have a number of vernal pools in Rouge Park with different elevations. South of that pond, just north of Warren road, on the east side of the river, the vernal pond that I have known for the last 4 years was empty most of spring, but those same rains that flooded Tireman vernal pond filled up the southernmost vernal pond in Rouge Park. Spring Ephemeral Flowers April showers bring us May flowers…. the spring ephemerals are fully in bloom! Ephemeral comes from the greek word ephemerus-meaning lasting a day or a short period of time. This early spring season is so special, before the trees fully leaf-out the forest floor comes alive with the tiny, short lived flowers, many of which move through their entire life cycle sprouting, flowering, pollinating and setting seed as the canopy above them fills out. Mutual benefits: A solid 40% of these ephemeral flowers count on ants to spread their seed, by producing seeds with fatty deposits on them, called elaiosomes, rich in lipids, proteins, and carbohydrates, which act as a high-energy food source for ants and their larva. Ants to collect them, eat the fatty part and deposit seeds in ant-dumps called middens where those seeds can safely germinate into more flowers!
The following are spring ephemerals I have personally encountered in Rouge Park with some interested facts about each. Please note that while some are edible, we request people refrain from harvesting in Rouge Park as we don't want to lose the population we are trying to preserve through unintentional overharvest. Spring Beauties (Claytonia virginica) are edible, and they range from white to pink. Pink flowers are more likely to be eaten but also more likely to attract pollinators. Blood Root (Sanguinaria canadensis) Purportedly, the red sap from the roots, from which it gets its name, was used as a natural dye and face paint by some Native American tribes. Modern science has found that it is toxic, causing irritation, burning, inflammation, and tissue death, forming thick, dark, scabby tissue. **Rare due to deer pressure. Dutchman’s Breeches (Dicentra cucullaria) Also toxic, the flowers lack fragrance are primarily pollinated by bumble bees, one of few insects big and strong enough to enter the flower. **Rare in Rouge due to deer pressure. Cut-leaf Toothwort (Cardamine concatenata) Pungent edible brassica, connected via rhizomatous roots which are spicy, giving the plant the name "pepper root.” There were historically used as medicine, food, and even as an indigenous "love medicine" by the Haudenosaunee peoples. Spring Cress (Cardamine bulbosa) same edible brassica family, lots of vitamin C, and a spicy, horseradish-like Rue Anemone (Thalictrum thalictroides) buttercup family, produces pollen and not nectar. Meadow Rue (thalictrum dioscorides) Wind pollinated, with weird dangling pollen sacks and petal-less flowers. Blue Cohosh (Caulophyllum thalictroides) Cohosh" comes from Algonquin for "rough," referring to the rhizome. Purportedly used by Native Americans for aiding childbirth (uterine stimulant), promoting menstruation, and as an anti-inflammatory. However modern medicine considers it toxic. Trout Lily (Yellow: Erythronium americanum, White: Erythronium albidum) Edible, Natives used for fever, wounds, and contraceptive, anti-inflammatory, antibacterial, and wound-healing properties. Eating in large quantities can cause vomiting. Only 10% are successfully pollinated, more spread asexually from bulblets that fall off the main corm. It takes 4-7 years to flower.. grows in colonies, some aging thousands of years old, age is measured by the size of their colonies. Wild ginger (Asarum canadense) Alleged that native used roots for flavoring, which smells like ginger but is NOT related. Modern science says consuming this is a bad idea, cause of toxic compounds in the plant. Yellow bell wart (Uvularia grandiflora) droopy aesthetic has earned it nicknames like "sad bells”. These guys can be big, as seen in the scientific name grand, but they tend to stay small and sad due to deer pressure. Trillium (Trillium spp) Can take up to 10 years to bloom from seed, these are ***decimated by deer because they are highly nutritious and apparently delicious, popping up in early spring. Jack in the pulpit (arisaema triphyllum) The trans-plants can change sex from male to female depending on environmental conditions and age. Pollinated by a fungus gnat, lured by the musty smell of fungi, they get stuck, hitting the central spadex as they try to fly away. Virginia Waterleaf (Hydrophyllum virginianum) The lighter, watery patches on the leaves, most prominent on young in spring, fade away, turning solid green as the summer progresses. May apple (Podophyllum peltatum) Rhizomatus so they grow together in colonies. Produce a fruit in late summer (not may) that is said to taste like a mix of pineapple, mango, and passion fruit. While the rest of the plant is toxic, the roots contain a compound used by the pharmaceutical industry to fight virus and cancer. Two leaves means flowers and fruits. Wild geraniums (Geranium Maculatum) Geranium = from Greek geranos (crane), referencing the long beak-like fruit, which explode once dried and ready, shooting the seeds up to 30 feet away, on a form of Ballochory (or ballistic seed dispersal). False lily of the valley (Maianthemum canadense) Like the mayapple one leaf means no flowers, and 2 leaves means flowers and fruit will come. **Rare due to deer pressure. The southern section of Rouge Park is an older growth forest, easily one of Detroit’s most intact natural areas; the giant trees, the abundance of spring ephemeral flowers and vernal pond… all very clear signs of old growth forest. But the forest could use a bit more tender love and care, in the form of invasive species control, deer management and controlled burns. I’ll talk more about the Southern Section of Rouge Park and these vital management changes next month!

Sugarbush ended early this year in mid March. The part I hold dearest of the sugarbush season is observing the changing forest, in the same place, on a regular basis. Watching an ecosystem come alive, observing the natural queues of the changing season, the phenology. I challenge you to get out into the same green space weekly or biweekly to watch Mother Nature wake up. Spring birding! The birds are back! In Detroit, some species never leave, leading more residential lives like Black-capped Chickadees, Northern Cardinals, Blue Jays, White-breasted Nuthatches, Grackles, Titmouse, Pigeons, Morning Doves, Red Tailed Hawks, Crows and several woodpecker species like Downy, Hairy, Pileated, Red-bellied. Check out the range maps below! Turkeys Speaking of resident species… Turkeys are out, the Tom’s (male turkey) aggressively strut their bright red, white, and blue head colors, producing gobbling sounds to establish dominance and to attract hens. They will be breeding this month and into April when they start to nest! Please give them ample space if you encounter a brave turkey! (see the video by local birder Donna Croaker Hall) Spring migration The Detroit & St Clair Straits are an international migratory corridor for millions of birds. Situated at the intersection of the Atlantic and Mississippi Flyways, the Great Lakes provide wonderful birding opportunities. The bird migration is triggered by changing weather, motivated by increasing insect populations, sprouting plants, and the desire to nest and mate. It starts at the end of winter and the beginning of spring, peaking in the month of May! Rouge Park is competing with the other major parks this spring for documenting bird species! Help make Rouge Park a big winner by downloading the E-bird app, identifying birds in Rouge park and signing up for this Bird Off. Red Winged Black Birds Spring migration often kicks off with Red winged black birds, the males arrive first, with their black plumage and showy orange/yellow shoulder pads. They fight to defend their largely wetland territories. Expressing major “sexual dimorphism” female Red Winged Black birds look very different! Many mistake female red winged blackbirds for song sparrows. Woodcocks American Woodcocks also return in late winter… I particularly love their “peent” calls that can be heard at night. Like so many other bird species, they’re entering their mating season. You can catch their distinct calls at dawn and dusk.. I bet you will recognize it. Check out their distinct bobbing movement here Sandhills Cranes & Greta Blue Herons As many of y’all know the Great Blue Herons have a rookery or group nesting site near Brennan Pools. Please observe from afar to avoid interrupting their spring mating and reproduction! A sandhill crane was spotted in the south section of Rouge Park at the new DSWD Far West Side Stormwater Improvement Pit! Once paired up, Sandhills cranes mate for life. Their mating season is also this March/April time of year. (see the photo by local birder Donna Croaker Hall) Other signs of spring… The first trees to flower, that I have seen, are the red and silver maples. But the buds of so many others are swelling and will pop this month, like spice bush, willows, elms, serviceberry, dogwoods, crab apples and redbuds. Ants The bugs are active… and popped up around the sugarbush buckets as early as late February… but they’re out in force by mid March. Ants are important because they play a crucial role in spreading the seeds of Spring Ephemeral Flowers through a process called myrmecochory, many spring forest flowers have seeds with fatty flesh that ants harvest, farm to feed fungi that they eat, simultaneously spreading those precious seeds. Ephemeral flowers
The ephemerals are sprouting, the first leafs that come out were called Cotyledons. By the end of April the older growth sections of Touge Park will be sprinkled with tiny white, yellow and pink flowers… trout lillies, spring beauties, cut leaf toothwort, wild ginger, flying Dutchman’s britches, wild geranium, bellwort… more on these later! We had a solid winter this year– steady snow cover and plenty of days below freezing. The landscape is still mostly brown, but life is beginning to stir. It’s maple harvest season, sugarbush time in Rouge Park. For generations, Native peoples have read ecological signs to mark the coming of sugarbush: the return of ravens, yellow-bellied sapsuckers, American robins, and red-winged blackbirds. Much like us, sapsuckers drill into trees to access sweet sap. In fact, I found a feather from the Yellow Bellied Sap Sucker when I first found this sugarbush location back in 2019 (see a photo from that day below). We’ll be birding in the Rouge this spring, so stay tuned.
Historically, many Indigenous communities across the Great Lakes region moved seasonally. In winter, smaller hunting camps would gather back together in early spring to boil maple sap. Through communal labor, they produced maple sugar to sustain them through the final stretch of winter. Bringing people together outdoors– for shared work and a little sweetness– is at the heart of our sugarbush project as well.
We hope you’ll join us for sugarbush workdays this March. More details can be found in the stewardship article. We had a solid winter this year– steady snow cover and plenty of days below freezing.

Measuring Empire What are the ways you measure time and the changing of seasons? Perhaps schools starting, the changing leaf color, corn harvests or Halloween. Markers aside, we measure time with the “Gregorian” calendar. While this way of measuring time is unremarkable to us, the story of expanding this calendar, and other standards of measurement, around the world is fascinatingly the story of empire. The Gregorian calendar was introduced by the Catholic Church under Pope Gregory XIII in 1582 after the Spanish reconquered the Iberian peninsula and began expanding into the Americas.. The British empire only adopted the more accurate calendar in 1752 when the British and French began edging out Spain. Russia only adopted it formally in 1917. Today it’s the most widely used calendar in the world for business, civil affairs and trade. Yet, to this day, billions around the world use alternative calendars for traditional seasonal activities and religious events. The indigenous peoples of the Great Lakes, the Anishinaabe, measured the year based on the moon cycles, contrary to our solar calendar. They refer to each moon cycle based on the environmental, social and ecological activity of that moon. Photo 1: The year in world calendars via The World in Maps, Photo 2: Anishinaabe Calendar by 14 First Nations of NW Ontario The last moon cycle was the Manoomin (Wild rice) Moon. In Anishinaabe creation stories, the creator instructed them, “to move west until they find the food that grows on water.”Manoomin is that sacred grain for Anishinaabe peoples. The state of Michigan actually just made manoomin the state grain in 2023. If you attended the Buffalo Soldiers and Blues Festival you may have observed me with a tarp-full of fresh wild rice! I had spent the previous few weeks harvesting up north. This ancient grain grows in clean, shallow, slow moving wetland ecosystems like in Tawas Lake. Historically, a profusion of wild rice could be found in growing coastal wetlands. A pristine example is the largest remaining coastal wild rice bed in the world, the Bad River reservation in northern Wisconsin. This is why the Bad River Reservation has been fighting mining and pipelines in their watershed, check out the documentary “Bad River.” Photo 3: Wild Rice at the Buffalo Soldiers Fest, Photo 4: Antonio Harvesting Wild Rice in northern Michigan Photo 5: Bad River Wetlands and watershed z_Mining_Penokee_ExploratoryDrillSite_Map_2011.jpg Wild rice is rare in Michigan because of wetland loss and environmental pollution, recurring themes in my articles. Wetlands are cornerstone ecosystems that prevent flooding, restore ground water levels, clean water, and provide essential habitat for wildlife. Wetlands loss in Wayne County exceeds 90%. It follows, our hyper-urbanized, drained and polluted watershed cannot sustain wild rice, the ecological context is almost the opposite of Bad River. Photo 6: Wild Rice, Photo 7: DEQ Wetlands Loss Rouge River is polluted by many sources; winter road salt; oil and grease drainage from streets; pesticides and fertilizers from lawns/golf courses; bacteria from pets and wildlife; heavy metals & PFAS from industry. One major ongoing source of pollution are the Combined Sewer Overflows(CSO’s) that continue to contaminate the river with human waste during large rain events. While much of the problem has been abated, the remaining CSO’s are very expensive to repair.. That unfortunately falls on working-class Wayne County residents. This is why we have received hardship exemptions from the federal government as our CSO’s violate Clean Water Act protections for bodies of water like the Rouge River. Federal government investments in local water infrastructure peaked in the 1970s around the passage of the Clean Water Act. We shouldn't expect much support from the Trump administration on this issue. Detroit Water and Sewage Department (DSWD) customers are not alone with our aging water infrastructure. Failing infrastructure is a national issue. The American Society of Civil Engineers graded America water related infrastructure poorly; drinking water receiving a C-, wastewater a D+, and stormwater a D. If the influence of an empire is “measured” through standardizing measurement around the world, what does the quality of water and sewage infrastructure say about a civilization? Combined Sewer Overflow’s are a big problem for the Rouge River. While there are many sources of pollution within our watershed; the road salt for winter safety; oil and grease from street drainage; pesticides and fertilizers from lawns/golf courses; bacteria from pets and wildlife; heavy metals &PFAS from industry. One major ongoing source of pollution are the Combined Sewer Overflows(CSO’s) that continue to contaminate the river with human waste during large rain events. The remaining CSO’s are very expensive to repair, particularly for the working class wayne county residents and Detroit Water and Sewage customers who will likely pay for these updates. This is why we have received hardship exemptions from the federal government as our CSO’s violate Clean Water Act protections for bodies of water like the Rouge River. Photo 8: CSO Diagram by getty, Photo 9: Figure 2‐6: Combined Sewer Drainage Areas via Alliance of Rouge Communities Photo 10: Billions of dollars invested in water infrastructure National: Local by the CBO While many in SE Michigan might not be able to participate in the Maanomin-Moon, our park features natural and man-made solutions for the shortcomings of our current water and sewage paradigm.
Rouge Park houses some of the last remaining bits of wetlands, forested-flood plain, and the largest prairie in the county and watershed. Our prairies and forests naturally store and sink upwards of 10’s of million gallons of water each year. Our Park also features the DSWD Far West Detroit Stormwater Improvement Project, construction you have surely noticed on the south western side of the park over the past few years. This project will reduce chronic basement flooding experienced by approximately 1,200 homes and will keep nearly 100 million gallons of stormwater out of the combined sewer system annually. You can be part of the solution too. A single individual can make a slight difference in the watershed problems:
But unfortunately there are no individual solutions to collective problems of this scale.. you gotta join a community or organization to work on these issues! Come volunteer with us at Friends of Rogue Park (FORP) to help maintain these forests and prairies. Removing invasive shrubs helps these ecosystems hold water in the long term as native plants tend to have much deeper roots. The Alliance of Rouge River Communities (ARC) to encourage watershed-wide cooperation and support to restore beneficial uses of the Rouge River, they create the tools, funding, and projects that residents, schools, and local organizations can plug into through local governments and other organizations. Many of you are probably engaged with Friends of the Rouge (the watershed or, FOR). They’re an excellent partner to follow in this effort to revive the Rouge River… FOR has been helping support residents in the creation of more than 100 rain gardens all over the watershed. Also, be on the look out for forthcoming Coalition for a Clean Rouge, an effort between multiple organizations in the watershed to advocate for alleviating our river of her CSO problems. And who knows, maybe we’ll bring some wild rice activities to the park in the future! Lots of youth, Weekly Workdays are Done. This summer we’ve had 3 different youth teams working in Rouge Park: Youth Work is a Civilian Conservation Corps crew from Child & Family Services of Northwestern Michigan. They worked primarily on the Scout Hollow Trail, opening up a view of the wetlands across the street from Brennan Pools, helping clean up a job we started with the ACCESS volunteers back in May. The crew is composed 4-5 younger Detroiters, and it is the program’s second year working in Rouge Park. Another crew that worked in the park were from the nonprofit, Green Door Initiative. GDI sent anywhere from 8-12 youth with crew leaders, completing more than eight workdays in the park. Their work centered on restoring a new section on the eastern side of the Ma'iingan Wildwood Trail connecting back to the Sorenson Rec reation Area. We made significant progress with their help! We’ve been training up a team of Lead Stewards to help support volunteers who come to work in our park. Thus far we have had 5 trainees, with another 5-7 new trainees joining the Lead Steward Training Program this August. They will represent Friends of Rouge Park to guests who come to volunteer in the park. These leaders shined when 80 youth from Greening of Detroit or the 150 from Americorps members came to work in the park. Their leadership has been vital. We recruited these stewards from consistent volunteers, so If you’re interested in being a lead steward; come hang out with us and put in some work. The summer was a sprint, and as the weather cools, our field work will shift. We will no longer be offering weekly public workdays on Fridays! But we are beginning our weekday volunteer days for those who can come on weekday mornings! The following are this September’s workday opportunities: Sept 10, 9am-12pm Corporate workday @ Tireman Ave & Spinoza Dr. Sept 17, 5-9pm Sunset workday followed by Night Moth activity @ North Prairie Pathway/Butterfly Garden Sept 25, 9-12pm Corporate Workday @ Tireman Ave & Spinoza Dr. Sept 26, 5-7:30pm Sugarbush Buckthorn Bonfire @ Outer Drive, South of Tireman Ave. Ecological Report: Goldenrods heals, prairies overrun by invasives need fire In these final days of summer, which officially ends on the autumnal equinox, Sept 22, the prairie is fully blooming with goldenrod. So far I have only observed five species of goldenrod; gray goldenrod (solidago nemoralis), grass-leaf goldenrod (euthamia graminifolia), stiff goldenrod (solidago rigida), late goldenrod (solidago altissima), and Canada goldenrod(solidago canadensis). I hope to see a few more now that they’re all starting to bloom. Goldenrod is a pioneering species, whose seeds spread through wind dispersal, making it excellent for soil stabilization. It’s also a vital late-season food source for pollinators like bees and butterflies, and beyond that, a food source for other animals, including birds (in winter) and small mammals (like deer & rabbit). As for its medicinal benefits, goldenrod contains anti-inflammatory, antiseptic, and diuretic properties, which make it effective for respiratory congestion, seasonal allergies, and wound healing. It can also be used for skin irritations, to reduce swelling and pain, and support urinary tract health. The invasive porcelain berries (Ampelopsis glandulosa) are now starting to show their purple and blue brilliance. Native to south east Asia, the plant was brought over for its ornamental value. Its berries are edible, yet unpalatable with flavor described as “bland, slimy, or mealy with a prickly aftertaste.” However birds will eat it when other foods get low. They are the primary means of spreading this invasive. We have yet to figure out how to manage these fellas but they are dominating the prairie. Their leaves are a lot like grape leaves but deeply lobed, separated into 3-5 sections. Look out for them if you are strolling through the beautiful goldenrods in our prairie. They cover most everything.
July & August are peak months for exploring Rouge Park’s restored prairie. Insects hum, birds forage, and wildflowers burst into bloom. On July 25, the season’s first goldenrod caught my eye, a sure sign we’re entering prairie high summer and that fall is right around the corner! Here are just a few of the standout species lighting up the landscape right now:
The prairie is not just a place of beauty—it’s a living library of botanical relationships, ecological strategies, and pollinator paradise. Come walk it while it’s loud with bloom and buzzing with life.
My biggest issue working in the field this month? Mosquito season. It’s in full swing—hot, wet, and buzzing. In Michigan, mosquito season typically runs from May to October, with peak activity from June through August. They thrive in warm, humid conditions, especially once temps stay above 60°F, and are most active in shady areas—often the same places overrun by invasive shrubs.
Mosquitoes played a major role in shaping Michigan’s history. They hindered early colonial settlement in Detroit and surrounding areas due to mosquito-borne illnesses, especially malaria. The Great Black Swamp in northeast Ohio prevented many from settling Waawiyaatanong (“curved shores”) aka Detroit. Researchers estimate malaria caused 50–75% of illnesses in Michigan prior to 1880. In response, colonizers aggressively drained wetlands—actions that now contribute to flooding, biodiversity loss, and declining water quality by disrupting nutrient sinks and groundwater recharge. This year, a student visiting the park asked if we could just kill all the mosquitoes. The answer? Technically yes—but should we? Mosquitoes serve critical ecological roles. As aquatic larvae, they feed fish, dragonfly nymphs, and other insects. As adults, they become food for birds, bats, frogs, lizards, and more. They also help transfer nutrients from aquatic to terrestrial ecosystems, linking different parts of the food web. We’re already deep in the “Great Insect Die-Off.” Some studies report up to a 75% drop in insect populations over recent decades. Many mosquito-control methods are nonspecific and risk harming pollinators and other vital insects. So yes—leave the mosquitos alone… and get better skin protection; we’re covered in bug jackets and masks while removing invasive and building trails this summer. One invasive we’re focused on eliminating is multiflora rose (Rosa multiflora), brought from Asia in the 1800s. It’s a dense, arching shrub that spreads aggressively by seed and suckers. Look for clusters of small white flowers (20+ per bunch) and leaves with 9+ leaflets and fringed stipules at the base. In contrast, native roses—like Rosa blanda, R. carolina, R. palustris, and R. setigera—are smaller, more open, and non-aggressive. They have pink flowers (usually solitary or in small groups), bloom mid-summer, and have 5–7 leaflets without fringed stipules. Lately, I’ve spotted plenty blooming around town: birdsfoot trefoil (invasive), chicory, fleabane, St. John’s wort, catalpa trees, knapweed (invasive), peonies, lilies, and lavender. And the prairie? It’s coming alive. I highly recommend hiking every few weeks to catch what’s blooming: common motherwort, Deptford pink, purple coneflower, black-eyed Susan, lance-leaf tickseed, bee balm, narrowleaf mountain mint, sulphur cinquefoil (invasive), yarrow, wild bergamot, verbena, ox-eye daisy (invasive), and butterfly weed. The lupines should pop soon. |
