Canadian perspective: Bright Wings Milkweed or Asclepias is a tropical cousin to our common milkweed. It is very beautiful and also a non-invasive cultivar of milkweed which help butterflies & pollinators. For us in Canada this is an amazing annual for use in gardens & containers. This mid to late summer heatlover has big clusters of 1 inch blossoms in vivid scarlet-red, warm orange-red & gold.
TO PLANT DIRECTLY IN THE GARDEN: Sow seed 4 to 5 inches apart in a finely textured, well-worked garden bed in full sun once danger of frost is past. Cover 1/4 inch deep and keep moist as seedlings emerge. Thin to stand 12 inches apart when seedlings are large enough to handle.
GROWING NOTES: Asclepias needs excellent drainage and full sun, but no extra fertilizer except in very poor soil. Use for warm color in sunny borders where these plants are butterfly magnets. Bright Wings plants are also lovely in large patio planters. For longest lasting cut flowers, harvest either very early or late in the day only after two thirds of the florets are open. Do not sear stems in hot water (unlike other Asclepias varieties).
