About Common, Milkweed Seed
The Common Asclepias, also known as Butterfly Weed or Common Milkweed, is the only plant that Monarch butterflies lay their eggs on! This variety provides an abundant food source for Monarchs, but have been declining in the recent years due in part to suburban development and the increased efficiency of herbicides. The Common Asclepias spreads readily by seed and underground rhizomes and its taproot can withstand drought. This Butterfly Weed is one of the easiest and fastest to establish of the Milkweeds. Enjoy watching beautiful Monarchs visit on a daily basis!

Tips
Pests & Diseases
Leaf spots, rust, powdery mildew, and root rot may occur. Provide airflow, avoid waterlogged soil, remove badly affected foliage, and clean tools between plants; discard material showing severe disease rather than composting it.
Aphids, milkweed bugs, spider mites, and oleander aphids may gather on stems and pods. Identify monarch eggs and caterpillars before acting, rinse or hand-remove pests when practical, and avoid systemic or broad-spectrum insecticides.

Its Role in the Native Ecosystem
Common Milkweed supports monarch caterpillars on its leaves and provides nectar for many flower-visiting insects. Its spreading colonies also sustain other milkweed-associated insects, forming a broader food web. Give it room to expand, and avoid unnecessary insecticide use that would undermine its role as a host plant.
