Asclepsis tuberosa or butterfly weed is a wonderful addition to the summer garden. Its bright orange flowers are irresistible to butterflies, especially the monarch. Although the flowers lure the monarch butterfly, the monarch caterpillar eats nothing but the foliage of this particular plant. One morning I discovered that the caterpillar had eaten every single leaf. Normally I would be heart sick to see a plant damaged but the presence of a monarch in the garden is a gift.
Despite being called a weed (milkweed more specifically), I do not consider it a weed. As a matter of fact, it is a well-behaved, easy - to - grow, beautiful perennial in the garden. After the blooms fade, green seedpods take their place. The seeds do eventually migrate through the air; this plant, however, seems only to have spread in my garden by forming larger clumps. Butterfly weed prefers full sun, although mine is doing very well in part sun. It is not a drought tolerant plant, but enjoys water during dry times.
Ascelpsis tuberosa provides a double gift for the gardener. It not only attracts flights of butterflies to the garden, but it also brightens any flower bed.
