Asclepias tuberosa

Share on

Common Name: Butterfly Weed

Full to part sun, medium to dry moisture level, prefers a fertile well-drained sandy loam, moderately acid to neutral pH.  1-2 ft. height, blooms in summer, orange flowers, slow re-seeder.

Germination Code:  C(30)

Native Region: Statewide

One of the showiest native wildflowers.  Colorful, hardy, long-lived and carefree. Slow to emerge in spring.  Has a deep tap root and resents disturbance.  Blooms for 8 to 10 weeks or more.  Should only be planted on upland sites because does not do well in poorly drained soils. Some seed companies offer an uncommon strain called a “clay buster” which is native to clay soils.  Attracts butterflies and bees, particularly a Monarch butterfly magnet.
