Its leaves have turned to vermillion, cranberry, apricot, and topaz that mix in with lingering chartreuse, while pendulous catkins form along the gray branches.
An upright, multi-stemmed shrub with a rounded top, it grows 8’-10‘ tall. It forms colonies by means of root sprouts, although it has never done so in my garden Before European settlement it was the most prominent shrub in the Chicago region. But the suppression of fire and the overgrowth of exotic honeysuckle and buckthorn has altered the composition of open savannas to the extent that American Hazelnut is rarely found in the wild any more. I’ve searched in vain in the Forest Preserves of northern Kane County where I live to see it in its native habitat. Fortunately, Hazelnut is readily available from nurseries and it makes a splendid shrub for home grounds. Group it in partial to full sun in a shrubbery border or plant it on the east or west corners of a house. Or grow it in a naturalized situation within an oak savanna, or along a woodland edge or a fence line. It produces downy clusters of edible nuts in September and October, similar, or some say superior, to the commercial variety. It is, however, difficult to harvest them before the critters do. Hazelnut can withstand fire, regenerating after the top has burned to the ground. It was a favorite of Jens Jensen— he frequently planted it in colonies within a shrubbery border along property edges.
The vibrant crimson leaves of the Black Haw (Viburnum prunefolium), situated on the other side of the savanna garden next to the sidewalk, is equally eye-catching. Growing 12-15’ tall and 8-12’ wide, the horizontal branching pattern of the tree is reminiscent of hawthorn trees:hence the name. Jens Jensen, for that reason, favored Black Haw, as well.
A tangle of colors, textures, and shapes creates a fascinating picture.
Aptly named, the golden-rayed, brown-centered daisies of Tall Coreopsis (Coreopsis tripteris) grow in branched clusters at the top of 6’-to-7’ tall, smooth, wand-like stems. Its 3-part leaves have turned to a magnificent wine color. At my house, it has never flowered beyond mid-September.
In nature it is found in prairies and thin sandy woods.
This is, by far, the latest that Prairie Baby’s Breath (Euphorbia corollata) has flowered, as well
The fall foliage of Prairie Baby’s Breath turns to gold; in a dry year it becomes scarlet.
One can never have too many Prairie Dropseed (Sporobolis heterolepis). The whorled, arching mound, 1’ to 2’ tall and up to 3‘ around turns a brassy gold at first, then becomes a coppery bronze. Delicate airy panicles of aromatic flowers begin to emerge in August on stiff stems 2-3’ above the foliage; the ripe seed drops by the end of September
The foliage of Smooth Blue Aster (Aster laevis)–oops! (Symphyotrichum leave) has turned to crimson.
Surprisingly, the leaves of the woodland, May-blooming Wild Geranium (Geranium maculatum) turn to scarlet in the fall. It’s surprising because, offhand, I can’t think of any other spring woodland wildflower that turns red in the fall..
Did I say one can never have too many Prairie Dropseed?.
The leaves of the Redbud trees (Cercis canadensis) create a ceiling and a sea of gold above and on my patio in October.
