Erect perennial of sandhills and other dry woodlands. | Stems stout, usually unbranched, smooth with a white-waxy coating; leaks milky sap when bruised. | Leaves opposite (2-6 pairs), sessile and clasping, oblong or widely oval to elliptic, 3-5 in. long, with a pink midrib, wavy-margined, smooth and with a white-waxy coating. | Flowers (15-80) in a rounded, terminal umbel; smoky purple, about 1/2 in. long, consisting of 5 strongly reflexed pinkish-green corolla lobes and a central crown--composed of 5 2-parted appendages ("hood" and "horn")--surrounding a complex structure of fused anthers and style. | Fruit an erect, spindle-shaped pod containing many tufted brown seeds. | 2-3 ft. | The flower clusters of the clasping, or sand milkweed are like those Styrofoam atomic model kits you might have put together for a school science project. Each pinkish purple tubular crown juts out from the reflexed green petals, all sit in a spherical orbit about a central point at the top of the stem. The large leaves are wavy with a pink midrib and clasp the stem. The fruit is a 4" long pod that will dry on the stem to release the tufted windblown seeds. This plant inhabits open woods, enjoys a sunny location with sandy, freely draining soil. | Erect perennial of sandhills and other dry woodlands. | Stems stout, usually unbranched, smooth with a white-waxy coating; leaks milky sap when bruised. | Leaves opposite (2-6 pairs), sessile and clasping, oblong or widely oval to elliptic, 3-5 in. long, with a pink midrib, wavy-margined, smooth and with a white-waxy coating. | Flowers (15-80) in a rounded, terminal umbel; smoky purple, about 1/2 in. long, consisting of 5 strongly reflexed pinkish-green corolla lobes and a central crown--composed of 5 2-parted appendages ("hood" and "horn")--surrounding a complex structure of fused anthers and style. | Fruit an erect, spindle-shaped pod containing many tufted brown seeds. | eastern United States |
