Phonetic Spelling

Description

Clasping Milkweed is a native perennial wildflower in the Apocynaceae (dogbane family) found commonly in sandhills or dry woodland areas.  It gets its common name because the base of the oppositely arranged leaves wraps around or "clasps" the stem.  This is a fairly rare milkweed and is protected in some states.

Clasping Milkweed is best for meadows/natural areas and it needs dry, sandy or gravelly soil.  The habit is upright with single unbranched stems and it has single rounded clusters of fragrant pink flowers that have cream or green in them and appear from late spring to mid-summer.

Insects, Diseases, and Other Plant Problems:  No serious problems.
