Detailed Information

Flower:

Flowers are in open droopy clusters at the end of naked stems that branch off the main stem in the upper part of the plant. Individual flowers are the typical milkweed shape: a crown of 5 curved horns and 5 sepals that bend back away from the flower. Each is about 3/8 inch across and ½ inch long. Flower color is creamy white to greenish or purplish. The sepals are light green. One plant usually has a few to several clusters.

Leaves and stem:

Leaves are large and broad, to 6 inches long and 3 inches wide, roughly oval to egg-shaped, tapering to a point at both ends with short leaf stems. Leaf edges may be slightly wavy, but are otherwise smooth. Attachment is opposite. The main stem is smooth and light green to purplish.
