Tropical Milkweed

Tropical Milkweed (Asclepias curassavica) is an introduced species here. It’s become popular in part because milkweeds are food for butterflies, including Monarch Butterflies, whose numbers have been falling for some time. However, there are questions about whether planting Tropical Milkweed is a good or bad thing.

One concern is that Tropical Milkweed’s perennial habit might be disrupting the Monarch’s epic migrations. Another concern is that the plant hosts Oe (Ophryocystis elektroscirrha), a parasite that adversely infects butterflies, and that is passed down to subsequent generations. This parasite is more prevalent in non-migratory butterflies such as those in Hawaii, but it’s not clear whether Hawaii’s population is suffering in the same way as some of those on the mainland. Hawaii’s Monarchs primarily use Crown Flowers to lay their eggs.
