A romp through Shanghai Prairie (part 2)

In my previous post about visiting Shanghai Prairie in Ann Arbor, Michigan, I discussed the background of the restored priaire and showed you some of what's growing there, including grasses and some fall-blooming flowers.

I didn't have the chance to show you everything, so here are some more photos from my visit on September 12, plus tips for how to incorporate these native plants into your own garden.

The prairie has subtle undulating elevations, due to the area previously being strip-mined. This means both plants that prefer wet soil (lower areas) and plants requiring very dry soil (higher areas) grow there.

Gray or old-field goldenrod (Solidago nemoralis) has green-gray fuzzy leaves and likes dry or well-drained soils. It doesn't mind clay soil, does well on slopes, and gets about two and a half feet tall.

Stiff or stiff-leaved goldenrod (Oligoneuron rigidum, formerly known as Solidago rigida) can get up to 5 feet tall. It prefers full sun and dry soil. The foliage is pale green with thick leaves extending perpendicular to the stem, and the flowers are a bit more showy than other goldenrods with more of a poofy shape than upright stalks.  

 
Great blue lobelia (Lobelia siphilitica) prefers moist or wet soil and part sun. It can handle full sun if it's in  extremely wet soil. It can reach 3 feet and attracts bumble bees. I like its blue flowers in the late season when most other blooms are yellow, pink, or white (in my garden, anyway). Alas, my soil is not wet enough to grow it, but if you have a bog or wetland, or are simply willing to water frequently, give it a try. Great blue lobelia is endangered in Massachusetts.

Nodding ladies'-tresses (Spiranthes cernua) is a native orchid. It grows only 8 to 12 inches tall, which is fairly unusual among the many taller plants in a prairie, and it's easy to miss it if you aren't specifically looking for it. It grows in consistently wet soil and prefers full sun.

Even this bad photo of American bittersweet (Celastrus scandens) will help you ID this native woody vine in comparison to the invasive variety, oriental bittersweet (Celastrus orbiculatus). Oriental bittersweet has flowers/berries in clusters of 2-3 in the leaf axils all along the vine, whereas American bittersweet has flowers/berries in clusters of 6 or more solely at the ends of the vine. The ripe berries of both are red, but the capsules, or protective covers over the berries, are yellow for oriental bittersweet and orange/red for American bittersweet.

Purple loosestrife (Lythrum salicaria) is an invasive plant that outcompetes other species in the prairie fen. Fortunately, it hasn't spread too much at Shanghai Prairie, with only this one major clump. (Random, unidentifiable human shown only for size reference.)

Like many other invasive plants, purple loosestrife is a "nitrogen fixer" that alters soil composition by releasing nitrogen and raising soil nutrents. There are instances where this is a good thing, like farmers planting cover crops (such as red clover and winter wheat) and tilling them into the soil before they go to seed to improve the soil for growing food crops. However, in prairies and other natural habitats, nitrogen is a bad thing. Native plants generally require poor soil conditions and do not grow as well in nitrogen-enhanced soil. (So if you grow prairie natives in your garden, it is not only not necessary, but also detrimental, to fertilize them!)

Lol, I'm suddenly picturing myself in a booth labeled "Plant Advice, 5 Cents." Ha!

Also fortunate for Shanghai Prairie is that purple loosetrife beetles (Galerucella spp.) are present. They eat  the leaves of purple loosetrife and help keep the population in check. The beetle was approved by the USDA in 1992 as a biological control, after research confirmed its host specificity at numerous test sites. In other words, it was determined the beetles only eat purple loosestrife leaves, not those of other plants, not even other (non-invasive) loosestrifes. 

The beetle has been released at trial sites in Michigan since 1994. They were not released into the Shanghai Prairie, but appeared on their own from nearby sites.

I can almost imagine a bunny holding one of these rabbit tobacco (Gnaphalium obtusifolium) flowers and smoking it like a cigar, except that in my mind, rabbits wouldn't smoke! The plant is sometimes also called sweet everlasting and it is supposedly fragrant (smelling like maple syrup), but I didn't bend down to smell it. The plant gets up to two feet tall and likes dry or well-drained soil.

Smooth or smooth-leaf aster, Symphyotrichum laeve (formerly known as Aster laevis; remember, the aster family got a huge naming overhaul!) prefers full sun but can handle some shade. It gets 2-3 feet tall and prefers dry to moderately dry soil. It does not mind clay. Its leaves are smoother, with an almost waxy feel, than those of a similar aster ...

...the New England aster (Symphyotrichum novae-angliae). The New England aster also gets taller, to 4 feet and above, and its flowers tend to be darker purple, than smooth aster. It also prefers full sun, but can handle some shade, and seems to deal with different kinds of soils. If you have these in ornamental beds with shorter plants, and want more uniform heights, you can cut them back on July 4 the same time you cut back mums. Mine self sow here and there and I like them towering over other plants.

The humble-looking Virginia snakeroot (Aristolochia serpentaria) is actually a rare and threatened species in Michigan, present in only two counties. It is an indicator species of a high quality oak woods. This one was growing in the wooded hillside near Shanghai Prairie. You cannot remove threatened species from their natural locations.

Hope you enjoyed your armchair romp through a prairie fen! If you are interested in seeing the prairie in person, you can attend upcoming volunteer workdays to help remove woody invasives:
- Sunday, October 16, noon to 4:00 p.m
- Saturday, October 22, 9:00 a.m. to 1:00 p.m.
Please wear long pants and sturdy closed toe shoes. To register and get directions (on campus of St. Joe Mercy Hospital), call volunteer steward Aunita Erskine at 734.668.6354 or email aunitafl at umich dot edu.

A romp through Shanghai Prairie (part 1)

Monday was bright, sunny, and unseasonably warm — a perfect day to romp around in a prairie. My friend Aunita Erskine took me on a tour of Shanghai Prairie in Ann Arbor near St. Joe's Hospital and Washtenaw Community College. She has been spearheading a restoration effort of this prairie for several years. Volunteers have been removing invasive species like buckthorn and autumn olive, and building boardwalks over wet areas.

The prairie covers about 35 acres between railroad tracks and the bend in the Huron River. It's considered a disturbed prairie remnant, with part dry to mesic soil conditions. The wetter part of the ecosystem is a prairie fen.

The prairie is in an area formerly inhabited by the Potawatomi, who called the area the Burnt River District. They regularly burned the area to create open spaces for the animals they hunted to graze. After the federal government bought the land, it was strip-mined for gravel. After that project was abandoned, vegetation returned, but many non-native and aggressive trees and shrubs filled in the space, outcompeting the grasses and prairie flowers. Later, sparks from the railway started little fires that killed the trees, and prairie plants again started to take a foothold.

Everything growing the the prairie today was in the prairie hundreds of years ago. Nothing has been reintroduced. Many prairie plants also make great garden plants.You can integrate native plants into your existing garden or create a new bed just for them.

Big bluestem grass (Andropogon gerardii) is sometimes called turkey foot. It reaches about 8 feet, prefers full sun, and does well in most soil conditions, except sand. It gets red in fall and is named for its green-blue color in spring. The seed head gets tiny yellow flowers which are quite striking in the fall landscape.

The prairie has several glacial erratics of varying sizes, which were washed in with the melting glaciers. Michigan is, by the way, the only state that was 100% covered in glaciers. It also means our soils are very random, from sand to clay to gravel in very short distances, sometimes in one yard.

Little bluestem grass (Schizachyrium scoparium) gets about 3 feet tall and is ideal for the home garden. It gets gorgeous reddish fall color, but is named for its green-blue color in spring. It prefers full sun, and can deal with most soils. It's not wild about clay, but it does OK in my very clay-y soil.

Indian grass (Sorghastrum nutans) looked so gorgeous covered in dew and swaying slightly in the breeze. It can reach 8 feet, but I've generally seen it top out at 6. Later in fall, its foliage turns dark orange/purpley. It is great for the home garden because it grows well in full sun to shade, and it can handle dry ot moist soil conditions.

Prairie dock (Silphium terebinthinaceum) is eaten by dear in the prairie and only the leaves remain. It normally gets 2 to 3-inch yellow flowers on very tall (up to 8 feet) stalks. It needs full sun and can handle moist to dry soil conditions. Give it a bit of space, as the leaves are huge.

Rough blazingstar (Liatris aspera). This grows well in the home garden, prefers full sun, and can handle most soil conditions except sand. It attracts birds and butterflies, and has the coolest looking pink-hued buds (the non-open flowers here are wilted flowers, not buds.)

There's just something about these gray-headed coneflower (Ratibida pinnata) seed heads! The plant gets about 4 feet tall, has yellow flowers with brown centers, prefers full sun, and likes most soil conditions, except sand. 

My absolute favorite things in the entire prairie were these gorgeous spent flowers of round-headed bush clover (Lespedeza capitata). It gets about 4 feet tall and prefers full sun, and mesic (average moisture) to dry soil conditions. The bloom is white.

Boneset (Eupatorium perfoliatum) gets about 3 feet tall and is a nice companion plant to Joe Pye weed. It attracts bees and butterflies, can handle full to part sun, and prefers moist soil. The leaves were used to treat dengue fever.

Heath aster (Symphyotrichum ericoides) is just starting to bloom. It's a wetland indicator species (meaning if you see one in the wild, it means you're in a wetland ecosystem) that gets about 2 feet tall and can also tolerate drier soils. It is resistant to deer browsing. Native Americans used heath asters to bind the structure of sweat lodges and on hot rocks to create herbal steam. This plant is threatened in Tennessee.

Sneezeweed or Helen's flower (Helenium autumnale) is one of my favorite fall flowers. Cultivars are available in burgundy ('Ruby Tuesday'), orange ('Orange Beauty'), and orange and yellow ('Mardi Gras'), but I also love the native yellow flowers. It grows to 4-5 feet tall and prefers full sun and moist soil; it flowers just as well in drier soils, but won't get as tall. Incidentally, it's called sneezeweed not because it causes allergies, but because Native Americans used it as snuff.

I can tell you're getting tired, so we'll break up our jaunt. Next time I'll show more prairie flowers, including a ladies' tresses orchid, as well as Virginia snakeroot, a threatened species growing in the nearby woodland.

Ruminastions

How did I get here?
This is not my beautiful garden.

These are not my beautiful nasturtiums.

Letting the days go by, into silent autumn
(with apologies to the Talking Heads)

This is ostensibly a Seed GROW post, but it's also a Sundries Sunday post so be ready for random ramblin' ruminastions!

nastiesTrellis090510

Well, my 'Spitfire' nasturtiums definitely look the worse for wear, especially after last night's low near 40! There isn't enough sun in this location; I've been needing to move a huge arborvitae. The hops is more or less gone, too, but look at the eeny beeny morning glory that popped up!

morningGlory

There are one or two more growing higher on the trellis.

astiesCorn090510

The nasturtiums I planted to grow up my corn are doing somewhat better. To all the hatas who tried to tell me I wouldn't get corn with only one plant, neener neener! I got two corn cobs, but neener neener on me, they were both covered with corn smut, which was so gross I tossed them before even taking a photo. I suspect it self-pollinated (with the seeds above falling on the tassels below). Everything in my garden has to fend for itself, lol.

turtlehead

Pretty turtlehead I received in spring from my friend Joey.

cupPlantOldBud

There's something about the forming seedhead of the cup plant I really like.

sunflowers090310

On July 4 I direct-sowed some zinnia and sunflower seeds. Two months later things are blooming.

pinkZinnia

I didn't used to like zinnias, but holla!



Ready to bloom any minute now...

sunflowerBee

...There we go! I can't help but smile when I look at sunflowers.

tomatoClip

My tomato crop was suboptimal this year, but I did discover an awesome plant tie: hair clips! Just make sure the ends don't pinch the stem. (These 'Great White' are high enough up to have (knock wood, toi toi toi) escaped the rascally raccoons so far.)

obedientMob

The obedient plant is kickin' ass and takin' names. Most of all mine for not dividing or staking it!



That's my girl!

oneHotMess

This corner of my huge front bed is the first thing I planted when I moved into the house. It is now one hot mess, with weeds encroaching the bed. The other side is even worse but I couldn't bear to show it!

notAsters

When the foliage of the goldenrod (I believe Solidago canadensis) came up, I thought it was native asters. It's not that I don't like goldenrod, it's just that there used to by be native asters in that space as well. The queen of the prairie is about to bloom, way later than the one in a sunny location out front.

bigBlueStemFunky

I couldn't get the contrast of Big Bluestem grass against the buckthorn in the background to work, so I did an inverse and messed with hue saturation. HA!

pi

Poison ivy growing up a stem of echinacea that the groundhog broke the top off of. Ah, nature. I have tons of small patches of PI like this and huge spreads. I've been hesitant to use Roundup because I often see American toads in this area and their skin is particularly sensitive to absorbing chemicals. Later in fall I'll paint it on.

dirtyGardener

We were talking on my facebook page about how some gardeners (volunteer at recent workday, left) seem to have a magic anti-dirt shield and others (me, right) very decidedly do not. Lisa pointed out in the comments that the woman to the left is holding pruners and so was likely standing while working. Which is a great observation and interpretation except that there happens to be very little to prune in that garden; mostly everyone was weeding and spreading mulch that day... and everyone finished clean, except me (though I was doing some more rigorous weed removal, lol!).

sweetAutumnClematis

I got this sweet autumn clematis (Clematis terniflora) from my mom two years ago and this is the first time it's bloomed for me. I winter-sowed two native versions of this plant, virgin's bower (Clematis virginia), and will be interested how long it takes them to bloom. (Where to plant them is a whole 'nother kettle o' fish.)

large milkweed bugs

Large milkweed bugs on (surprisingly enough) my milkweed seedpods.

Big Box Shrubs, Yes I Do!

A while ago I won some cool stuff, including a $20 gift certificate to Lowe's, from Lisa. Even though I had every intention of spending the money on bird seed, I couldn't resist these $3.33 gallon shrubs: two false cypress, two different cultivars of chokeberry, a spirea, and a red-flowered potentilla. No, I have no clue where they'll go.

elephantEarsBIG

My elephant's ears 'Illustris' really came into their own this year; they about quadrupled in size. They're gonna need a new pot before they come back in for the winter. Eep.

SiegyGert

I've shown Pinky a few times. These are Siegfried (left) and Gertrude. G is named partly after Ms. Jekyll (I chuckle to myself as she hated fuchsia) and partly after my grandmother.

flamingoTrailer

I wonder if I can get Siegi and Gerti to balance on a tight rope like these two? I adore everything about this photo of the Flamingo Trailer Court on Middlebelt Rd. in Farmington Hills, MI.


I'm growing Nasturtium 'Spitfire' for the GROW project. Thanks to Renee's Garden for the seeds.

August Blooms

I was just thinking it's been a while since we've walked around my garden together and it's even time for the August Garden Bloggers' Bloom Day!

chairPlanter

I have to start with this retro green and rusted lawn chair, which I found curbside. I struggled with at least five contortions before fitting it into my non-hatchback Focus. At one point it fell out of the trunk and was dragging on the road (I am not exaggerating)... and it hit my foot on one lift. But I'm stubborn and just knew it would make the perfect plant stand for my pot of elephant ears, ferns, and coleus.

BintjeInTub080110

I grew potatoes for the first time this year. I decided to use a storage tub (with holes drilled in the bottom), so I could fill it with composty goodness. You know they're ready to harvest when the foliage dies. I started them from seed potatoes, and they were ridiculously easy to grow and they tasted so good. And digging for the taters was fun — there's just something about sticking your arms elbow deep into a nice soil-compost mix and rooting around... aaaahhh!

BintjeSecondHarvest080110

Here's my second harvest of 'Bintje' potatoes. Nom nom nom!

BlackBeauty081410

I'd more or less given up getting eggplants this year, when I saw a tiny 2-inch fruit on August 8. Holla! I thought it was solely because, as Lisa put it, they were "abused as a seedling" (I left them in those small cell packs way too long before transplanting), but it turns out several others have reported their eggplants are late this year too (Ha! it's not all my fault!). We had a really heavy rainstorm and on August 14, the eggplant had tripled in size.

tomatoes

Tomatoes are looking a little small compared to everyone else's, but I don't have too much sun and the soil is bad here, despite improvements, so I'm glad to get even a few tomatoes per plant. They're all heirlooms and each plant is a different variety. I have another two tomatoes in the ground out of view, plus five more in containers. I just realized this whole shot, with my home-made compost bin and rain barrels, plus the random stuff I have set around to squelch weeds, makes this an excellent #uglygardens vignette.

I've saved my first tomato seeds of the season. Easy-to-follow tomato seed saving instructions, with photos, are here. This is my second year saving tomato seeds. I first used paper towels to dry the seeds in the final step, but the seeds really stuck to that. I then tried plain white paper and that worked a lot better. This year I found Colleen's instructions and I got some paper plates, which was genius. No sticking at all and much faster drying times.

The other thing I did differently this year was to wait for mold to form in the initial seed soaking. This fermentation step isn't necessary in terms of seed viability or vitality, but it makes the seed coating (gooey tomato gel) come off the seeds much more easily. Last year I skipped that step and rinsed and rinsed and rinsed and rinsed in a sieve. That worked, too, but was a lot more work.

cupPlant081110

My cup plant (Silphium perfoliatum*) is only 5 feet tall, though they can get to 10 feet in optimal sun. I wrote a bit more about it here.

cupPlantBug2

Look who I found on the cup plant blossom — the soldier beetle is not only a pollinator, but it eats aphids. I love beneficial insects. Plus, it's just so cute!

noddingWildOnion

Despite my laziness in not having planted this nodding wild onion (Allium cernuum) since my friend gave it to me in {looks around furtively} early June, it's blooming and doing well!

LiatrisAspera

I love the almost-ready-to-bloom buds of rough blazing star, Liatris aspera.

Big Bluestem

Love the turkey-foot shaped seed head of big bluestem grass, Andropogon gerardii.

tallCoreopsisFence

I have several clumps of tall coreopsis (Coreopsis tripteris), this one along the neighbor's fence.

butterflyBush

Butterfly bush is bright and cheerful.

ViburnumBerries

One of my many cultivar Viburnums. I love the berries. I do have a native arrowwood Viburnum, too. :)

AnemoneBuds

I adore the buds of Japanese anemone. (All together now: "Noogie!")

AnemoneFront

Some of my Japanese anemone have already starting blooming.

beautyberryBerries

The berries on this purple beautyberry shrub will turn bright, vivid, holla! violet in another month or so.

FrontLookingSouth081410_2

The front bed taken from the driveway, looking south. (Pinky says hi.)

FrontLookingSouth081410

The front bed along the house, taken from the porch facing south.

BiziFront

The front bed on the other side of the walkway, taken from the front porch looking west. (Say hi to Bizi** so she can ignore you!)

front

One of my favorite garden spots. I love the rattlesnake master (Eryngium yuccifolium) paired with the Russian sage.

RmasterRsage

And that combo close up.

MexicanHat
Mexican hat.

sunflowers081410

The sunflowers I sowed on July 4 are about a foot tall and look like they're getting buds!

MexicanPetunia

The Mexican petunia Sweetbay sent back in May finally has a bloom!!

RosaGoldenWings

My first-ever rose 'Golden Wings' is blooming again since I pruned the dogwood, which was blocking her sun, waaaaay back.

HeleniumOrange

Even though I cut my sneezeweed back over a foot in early July, it's blooming now. 'Mardi Gras' has long since finished, and now it's time for 'Moerheim Beauty'...

HeleniumNative

...and the native yellow Helenium autumnale. It's tall and makes a great screen for one of my rain barrels. (See how you can't see it?)

HeleniumNativeClose

I just love it close up.

dahliaBees

Bees love my dahlia 'Bonne Esperance.'

Kuri081410

I'd say my one (and only) 'Uchiki Kuri' squash is ready.

ironweed080910

The ironweed (Vernonia missurica) outside my front door is a good six feet tall. I've read it likes it wet, though I never water mine. I also read it can spread, but mine hasn't (though it is true I collect its seeds).

ironweedClose

I love its vibrant purple flowers.

And that's about it for today. It's too humid and there are too many mosquitos. Let's go in and have some zucchini bread and lemonade.

* I'm marking native plants in this post by also giving their Latin name. (No Latin name = not a native plant.)

** Bizi is Fiona's nickname; Jimi is James' nickname. People often mention "all your cats" and as much as I'd love to be a crazy cat lady, I have just those two. It hit me that perhaps the nicknames were interpreted as individuals, esp. as Bizi isn't so obviously derived from Fiona.

Thanks to Carol of May Dreams Gardens for hosting Garden Bloggers' Bloom Day.
