Want to help increase the Monarch butterfly population (Danaus plexippus)? Want more pollinators to visit? Milkweed (Asclepias incarnata) will not only entice adults but as a larval host for Danaus spp. will get them to stay in your garden to lay eggs and start the next generation.
This self-seeding perennial is also a larval host for the queen butterfly (D. gilippus) and soldier butterfly (D. eresimus).
A Native Milkweed Research Update indicates that use of the Non-native Tropical Milkweed (A. currasivica), the most common commercially available milkweed may have undesirable affects on monarch populations.

Daniels, Ph.D., Assistant Curator of Lepidoptera, University of Florida IFAS Assistant Professor of Entomology, Florida Museum of Natural History: http://www.floridanativenurseries.org/info/native-news/native-milkweed-research-update/
If you raise butterflies, In order to assure healthy adult Monarchs, follow Monarch Watch’s instructions to avoid passing on the parasite Ophryocystis elektroscirrha. http://www.monarchwatch.org/biology/control.htm
