The Butterfly milkweed produces many bright orange, flat-topped flower clusters from late spring through late summer. It is a host plant for the famous monarch butterfly. The milkweed provides lots of nectar for the adult butterfly and this serves as home and a food source for monarch caterpillars.
This plant thrives in average or dry soil and prefers full sun. Butterfly milkweed is best to establish as a young plant. Because it has a large taproot, mature plants of the butterfly milkweed are not easy to transplant. Once established, butterfly milkweeds will self seed if seedpods are not removed.
Asclepius tuberose is a great choice for a meadow garden. If you are looking to pair it with other plants, look at native grasses and wildflowers, such as asters and purple coneflowers (Encinacea purpurea), to a create a butterfly habitat. In a perennial border, pair it with lilies (Kniphofia) and other fiery flowers, or with cooler blues and purples, such as a veronica plant.
Problem and Solution: The main pest is the aphids that cluster at the top of the plant. To remedy this problem, just knock them off with a strong spray of water every two or three days for a week.
