Klehm Arboretum and Botanic Garden

Rockford, Illinois

Since late March I have been dropping by Klehm once or twice a week to watch the trees and wildflowers bloom. There's always something new. Click the photos for larger versions. And if you're in the Rockford area, be sure to stop by Klehm and do some exploring of your own.

Forgive my weak attempts at photography and, even more, my forays into wildflower identification. If I have it wrong, please let me know!

Yellow Sweet Clover

Melilotus officinalis
May 29, 2010

Here's a close-up (not awfully sharp) of the tiny flowers:

Mouse-ear Chickweed

Cerastium fontanum
possibly Grey Chickweed, Cerastium brachypetalum
May 29, 2010

Yellow Wood Sorrel

alt Sour Grass
Oxalis stricta
May 29, 2010

Daisy Fleabane

Erigeron annuus
May 29, 2010

Rough-fruited Cinquefoil

Potentilla recta
May 29, 2010

Daisies!

Oxeye Daisy
Leucanthemum vulgare

Red Clover

Trifolium pratense

Mayapple

alt Hogapple, Indian apple, Mayflower, Umbrella plant, Wild lemon, Wild mandrake, American mandrake
Podophyllum peltatum
May 19, 2010
 
Most flowers are shameless about strutting their stuff, but this one hides out beneath a dense mat of foot-high foliage. It's pollinated by bumblebees and other bees, perhaps by mistake as it has no nectar. There seems to be a minor academic sub-industry studying the pollination of this thing.
 
Altho the flowers bloom in May, the fruit appears and ripens later in the summer. It's edible in small quantities when ripe, but toxic in large amounts. Sort of like mercury, I guess (if you ask the coal industry). I think I'll pass.
 
Here's a look at the foliage:

Waterleaf

Hydrophyllum
May 19, 2010

Species not certain. I want to say Virginia waterleaf (H. virginianum); it's that or one of several very similar waterleaf species. Some of my photos suggest these were intermixed with a more broadleaved (less deeply lobed) species. If so, the bossoms were identical to my eye and I confused them at the time.

Here's another look:

Dame's Rocket

alt Damask Violet, Dame’s Violet, Dames-wort, Dame’s Gilliflower, Night Scented Gilliflower, Queen’s Gilliflower, Rogue’s Gilliflower, Summer Lilac, Sweet Rocket, Mother-of-the-evening, Winter Gilliflower
Hesperis matronalis
May 19, 2010

Dianthus

Dianthus, species unknown, similar to Dianthus barbatus
May 19, 2010

This amazing creature had me stumped (thistle with a petunia on top?) until a suggestion from my friend Galina pointed me to dianthus.

False Solomon's Seal

alt Treacleberry, Solomon's plume, False Spikenard
Maianthemum racemosum or Smilacina racemosa
May 19, 2010

Note the differences from Starry False Solomon's Seal: smaller flowers, more densely packed; wavy leaf edges.

Pussytoes

alt Catsfoot
Antennaria...
April 28, 2010

Not sure which of the many species this is. To me, it most resembles Alpine (alt Rocky Mountain) Pussytoes (Antennaria alpina) or Little-leaf Pussytoes (Antennaria parvifolia).

A bit more mature than last week, but possibly still not fully in bloom. They really do look like a cat's toes.

Starry False Solomon's Seal

Maianthemum stellatum or Smilacina stellata var. crassa
April 28, 2010

Authorities differ on the genus. Just beginning to blossom.

Swamp Buttercup

Ranunculus hispidus
April 28, 2010

Merry Bells

Uvularia grandiflorum
April 28, 2010

Any ideas???

April 28, 2010

Can't find anything in my Audubon guide that looks like this tiny blossom. I love the pink anthers.

While we're at it...

April 28, 2010

Any idea what this might be?

Purple Trillium

alt Stinking Benjamin
Trillium erectum
April 28, 2010

This gorgeous guy is supposed to be stinky (to attract flies), but I smelt nuttin'. The flowers aren't even fully open, and ain't he a beaut?

Roses are red, violets are...

Yellow Violet
Viola eriocarpa
April 28, 2010


Canada Violet
Viola canadensis

Common Buttercup

alt Tall Buttercup
Ranuculus acris

Poet's Daffodil

alt Nargis, Pheasant's Eye, Findern Flower, Pinkster Lily
Narcissus poeticus
April 20, 2010

A variety of Narcissus. Thanks to Betsy Rogers for the ID!


The colorful center feature is not dozens of stamens splayed out ala Busby Berkeley. It's a daffodil-like cup, mostly flattened.

In their habitat, behind some bluebells:

Pussytoes?

April 20, 2010

This may be a variety of pussytoes (Antennaria) or it may be something else. In either case I don't believe the blossoms are fully opened.

I hope I can find them again.

Common Wintercress

Barbarea vulgaris
April 20, 2010

A mustard. Flowers and young leaves are edible. Of course cyanide is edible, if you have no immediate plans.

Common Dandelion

Taraxacum officinale
April 20, 2010
