This tropical milkweed is hardy in zones 8-11 and grown as an annual elsewhere. Prefers full sun but will grow in partial shade. Plants thrive in well-drained, medium moisture soils. Once established, will tolerate drought.

 

Cultivation

 

Seeds can be started indoors 8-10 weeks before the last frost date. Sow seeds 1/8" deep and 6-8" apart. Optimal soil temperature for germination is 65-80˚F. Seeds will sprout in 21-28 days. Thin seedlings so that mature plants are 24-36" apart. Transplant outdoors once the danger of frost has passed.
