Several years ago, in July, 1999, I saw two extraordinarily beautiful native shrubs in bloom at the Chicago Botanic Garden that I had never seen before.
They are in bloom now–what would you guess?
Maybe you have never heard of them before either.
The first is Prairie or Illinois Rose (Rosa setigera) .

The Illinois Rose, also called Prairie Rose or Michigan Rose, is the latest blooming and showiest of our native roses. Abundant clusters of slightly fragrant, deep pink blossoms, 2 1/2 “ across, centered with golden stamens, cover the heavily armed canes from late June through mid-July. Emerald green, heavily veined, tri-parted leaves make a contrasting background to the flowers.
The canes may extend to 15’ or more in a season, making it a good candidate to train over a trellis, along a fence, or to cascade down a hill. It may also be grown as a shrub 5-6’ tall and around by clipping off the long canes.
In nature it is found along woodland edges and in savanna openings, frequently with Iowa Crab and Wild Plum. It is especially abundant and showy in the limestone area of the lower Des Plaines River valley, say Swink and Wilhelm. (Does anyone have a photograph of this to share?)
Here are some ways you can use them in your garden.
Climbing up a trellis.
Along a fence line
Cascade down a slope
In a vase. The blossoms become a deeper pink when they are in the house.
The other shrub is Purple-flowering Raspberry (Rubus odoratus)
The blossoms of Purple-flowering Raspberry are, quite simply, ravishing! This photograph has not been color altered–the flowers really are this gorgeous. Loose clusters of the luscious violet flowers centered with pale golden stamens appear in June and continue through July and sporadically into August. Small, flat, red raspberries form in August and September–regrettably not as sweet and juicy as the more common Black Raspberry. Its large maple-like leaves make a statement of their own and turn golden in autumn. It increases slowly by underground stamens.
I’ve never seen it in the wild–it doesn’t appear to be native to Kane County where I live.
Combine Purple-flowering Raspberry with Showy Tick Trefoil, in bloom now also, in a part-shade situation.
Look on pages 26-31 in my book, Design Your Natural Midwest Garden, to see and read about a north-facing entrance garden that features the above plants. Also look at the Jens Jensen back yard designs on pages 148-157 and the Fencerow design for more uses of the Illinois Rose and Purple-flowering Raspberry.
Both these shrub provide food and shelter for wildlife. Regrettably, both are also susceptible to Japanese Beetles.
