Prairie Dropseed

Family:  Poaceae

Scientific Name:  Sporobolus heterolepis

This perennial prairie grass is native to the Central and Eastern United States and Canada.  It requires full sun and prefers well-drained soils.  For that reason, it’s also extremely drought-tolerant.  Prairie Dropseed occurs commonly in prairies and along roads and gets its name from the tiny rounded seeds which drop to the ground in autumn.

Watch for: Small clumps of this grass with fine, hair-like green leaves up to 20 inches long that form an arching foliage mound  2-3 feet tall.  Foliage turns golden/orange in the fall, and a light bronze in winter.  Prairie Dropseed blooms in late summer, forming open, branching flower panicles on slender stems which rise well above the foliage clump.  Flowers are rusty-tan and noted for their unique fragrance (notes of coriander).

Other names: Northern Dropseed

History: Sporobolus heterolepis is a native Minnesota species.  It was one of the first plants used in prairie restorations as it is heat and drought tolerant and does well in habitats with naturally-occurring fires.  Native Americans ground the seeds of Prairie Dropseed to make a tasty flour.

Tidbits: Prairie Dropseed is a favorite of small rodents, which burrow in the tufts of leaves.  It’s a larval food plant of the Leonard’s Skipper butterfly and the nutrition-packed seeds attract birds throughout the winter.

Gardens/Cultivation: An attractive plant for any raingarden or green roof, Sporobolus heterolepis is slow growing and requires little maintenance.  It serves as great ground cover for hot, dry areas and is considered by many to be the most handsome of the prairie grasses, due partly to its “tidy size”.  This grass should be planted 18-24″ apart.

Queen of the Prairie

Family:  Rosaceae

Scientific Name: Filipendula rubra

Queen of the Prairie is a rare, native perennial that favors high quality habitat.  Named filum for “thread” and pendulus for “hanging”, this plant’s name refers to some species’ small tubers strung together by fibrous roots.  It thrives in full sun, wet to moderate moisture, and sandy to loamy soil and is often seen in meadows, prairies, and woods.

Watch for: An erect perennial, 3-6 feet tall.  The flower is a showy pink inflorescence on a long naked stalk and blooms June-July.  While blooming, the flowers look a lot like wind-tossed pink fluff. The central stem is smooth and has a tendency to look reddish in the sunlight.  Leaves are alternate, compound, and can be up to 2 feet long.  Each leaf has 1-7 palmate leaflets with coarsely dentate margins.

Other names: Filipendula

History: The root of this native Minnesota species has been used throughout history to treat various heart troubles and has also been used as a love medicine as it’s considered an herbal aphrodisiac.  In addition, it can be used to treat skin rashes as the root has a high tannin content.

Tidbits: The Queen of the Prairie is a very interesting plant.  It produces pollen favored by bees, beetles, and flies, but doesn’t create any nectar!  It’s also very useful for restoring fields as it is an indicator of high quality habitats.

Gardens/Cultivation: Filipendula rubra prefers the cooler climate of the Great Lake region to hot, dry summer heat.  Leaves can become spotted from foliar disease, but the plant is otherwise not subject to diseases or fungus and the foliage is not commonly eaten by deer or other herbivores.  Deadheading is not necessary as the flower heads are decorative and it does little to encourage rebloom.  If division is necessary, it’s best to divide this plant in the fall.
