Common Buttonbush along the Little Miami River...

A few weeks ago Matty and I went up to Spring Valley Wildlife Area along the Little Miami River with our sketchbooks. We spent the afternoon rambling about, sketching whatever we saw. When we came across a stand of Common Buttonbush (Cephalanthus occidentalis), we stopped and studied the tree and its blossoms, noting that the leaves occurred in whorls of three, and the "honey bell" was made of hundreds of tiny blossoms...

A Buttonbush inflorescence is a grouping of small flowers. The projecting needle-like styles create the starburst.
Common Buttonbush flower ball, also called a honey bell, dangles from a stem and looks a lot like a firework display, a starburst...or in a less romantic view, a pin cushion! 

Common Buttonbush is native to Ohio. It loves water and swampy areas, and true to form, we found a large colony hugging the edge of the lake and another in a low boggy area beside the lake, just steps from the Little Miami River. The flower balls were intensely fragrant, which is where it gets its nickname "honey bell" or "honey-ball," and butterflies were everywhere...

A female dark morph Eastern Tiger Swallowtail (Papilio glaucus) nectars on a Buttonbush flower-ball (inflorescence). The butterfly uses its proboscis to sip nectar from each tiny perfect flower and pollinates the florets in the process. 

Silver-spotted Skippers and Tiger Swallowtails were all over these flowers.
Two Silver-spotted Skippers (Epargyreus clarus) cling to the pin cushion for a sip of nectar as well. The long, projecting styles of each perfect flower in the inflorescence create the pin-like, starburst look.

The cranberry red stems of a Common Buttonbush shrub are almost as striking as its flowers. Its leaves have both a three-stemmed whorled arrangement (often near the flower) and an opposite arrangement elsewhere on the shrub.

Before the inflorescence bursts open, the tiny flowers (florets) are encased in tight mint-green buds (sepals). Here the flowers are just starting to open, but you can still see remnants of some of the buds and the light-green color.

After the flower petals have fallen away, little ball-shaped seed heads remain. Some will hold on through the autumn and winter. Each tiny flower in the inflorescence produces two seeds called nutlets. Often buttonbush trees grow at the edge of ponds, lakes, streams and rivers (or even in the water), so when the nutlets ripen and tumble out, they float and are dispersed by the currents. Wood Ducks, Mallards, teal, and other waterfowl like to eat the nutlets.  

For more information on the Common Buttonbush, including its historical use as a quinine substitute for malaria, look in "The Book of Swamp and Bog; Trees, Shrubs, and Wildflowers of Eastern Freshwater Wetlands," by John Eastman, pgs 34-37. For an online resource, click here for a link to The Hilton Pond Center's website, or here for the Ohio Department of Natural Resources Division of Forestry website.

What is an inflorescence?
When you look closely at a Buttonbush flower you'll notice it's a collection of hundreds of tiny flowers, called florets. Each one of the florets in the collection is a "perfect flower," which means it has a pistil (stigma, style and ovary) and stamens (anther and filament). The collection or grouping of florets is called an inflorescence. Common flowers with inflorescences are sunflowers and all the flowers in the daisy family. Click here for a past post called "Hummingbirds and sunflowers" that describes an inflorescence in more detail.

Blue eyes winking along the Little Miami River...

...but they're not mine, my eyes are green! These eyes are the tiny flowers of Blue-eyed Grass, a delicate flower in the iris family. The unassuming blossoms of Blue-eyed Grass often go unnoticed where it hides in wet prairies and sunny forest edges. "Sweet" best describes these soft blue blooms that nod on elegant long stems whenever a breeze catches them..

Blue-eyed Grass is a native perennial that hides along the Little Miami River on both sides of the bike trail. 

Even though Blue-eyed Grass is a member of the iris family, it's easy to understand why its common name marks it as grass. The leaves and stems are flat with parallel veining, just like blades of grass.

Although it has grass in its name, and its flat stems and leaves look like blades of grass, Blue-eyed Grass is actually a member of the iris family. 
What makes an iris an iris?
The parts on an iris always come in groups of three, so it's misleading when you first look at this flower. It appears to have six petals, but really it has three petals and three sepals that look just like the petals. (Usually sepals are green. They encase the flower when it's a bud. When petals and sepals look alike, they are called tepals. So our little flower has six tepals.) It also has three stamens, but with Blue-eyed Grass the yellow stamens in the center of the flower are close together and appear as one. (Botany in a Day, p 201, by Thomas J. Expel).

The delicate flower of Blue-eyed Grass nods in the gentle breezes of late spring.


Blue-eyed Grass closes up as the day progresses. I photographed these flowers in the early afternoon, and they were still going strong. In another couple of hours, the blooms would have closed.


Blue-eyed Grass

I love the poem "Blue-eyed Grass," by Mary Austin. It appears in her book, The Road to the Spring (collected poems), but a notation in the book said the poem was also published in St. Nicholas (a children's magazine) in the June 1904 issue, and it was slightly different. I found a bound collection of the 1904 issues of the magazine on Amazon and ordered it so I could see the differences. I always liked the poem in The Road to Spring, but after reading the version in St. Nicholas, I might like it more. You can decided which version you like better:

Blue-Eyed Grass                                              Blue-Eyed Grass 

BLUE-EYED grass in the meadow                           BLUE-EYED grass in the meadow
    And yarrow-blooms on the hill,                                 And yarrow-blooms on the hill,
Cattails that rustle and whisper,                                 Cattails that rustle and whisper,
    And winds that are never still;                                   And winds that are never still;

Blue-eyed grass in the meadow,                                Blue-eyed grass in the meadow,
    A linnet's nest near by,                                               And the laden bee's low hum,
Blackbirds caroling clearly                                        Milkweed that runs to be first in the field
    Somewhere between earth and sky;                          Before the butterflies come;

Blue-eyed grass in the meadow,                                Watersnakes making lacy rings
    And the laden bee's low hum,                                   Round a cardinal-flower's red spear,
Milkweeds all by the roadside,                                 And blue-eyed grass in the meadow
    To tell us summer is come.                                       To mark the noon of the year!

Great Plains Ladies' Tresses orchid (Spiranthes magnicamporum)...and a Great Egret...

I found this cool-looking orchid growing at East Harbor State Park near Lakeside, Ohio back in September when I was at the Midwest Birding Symposium. The long spikes of bright white flowers stood out and were striking against the surrounding greenery...

...tall spikes of Great Plains Ladies' Tresses (Spiranthes magnicamporum) grew along a path by a small pond near Lake Erie. Further down the path, several more plants were scattered through a soggy field along a boardwalk. The bright, bright white of the spiraling flowers popped wherever it stood.

Originally I thought this was Nodding Ladies' Tresses (Spiranthes cernua), but Andrew at The Natural Treasures of Ohio blog let me know it's Great Plains. Thanks, Andrew! Click here for a nice article to help you tell them apart. Apparently, Great Plains Ladies' Tresses are more fragrant than Nodding Ladies' Tresses. I don't remember them being fragrant, but we were looking for birds, and I had my long lens with me, so to photograph them, I couldn't get that close!

...adjacent to the tall, lanky and showy white orchid was a pond where an equally tall, lanky and showy white creature stood. The Great Egret, fishing in a sea of green, was the flower's perfect complement...

...spiraling upward in a double column, the flowers of the native Great Plains Ladies' Tresses form what looks like a braid and accounts for its common name.

Like all orchids, Great Plains Ladies' Tresses requires a specific species of fungus for normal growth and forms a symbiotic association between the root tissue and the fungus (click here for more information).

...love that frilly lacy ruffle!

...the egret continued to fish while I admired both him and the beautiful white flowers growing in a tight spiral.

I photographed this flower on September 17, 2011 while at the Midwest Birding Symposium.
