Asclepiadaceae
Milkweed Family
Asclepias incarnata L.
- Notes: Asclepias incarnata is taller than common milkweed, up to 5’, with only a line of hairs on the stem. The leaves are long and narrow, 5” by 1/2”, tapering at both ends, and are sparsely hairy. Umbels are terminal and from the upper axils, forming a corymbiform inflorescence of about 30 flowers per cluster. Flowers are pink to red. Fruits are shorter and narrower, 3” by 3/8”, and beaked for one-third the length. Flowering begins in early July and continues until early August; fruiting begins in late July, and seeds are shed in September. A. incarnata is common on marshes and on lowland prairies.
