whorled milkweed

Asclepias verticillata

According to the website Monarch Butterfly Garden, you shouldn’t rely on it as your main milkweed source for caterpillars, or you may run out of milkweed by mid-season. Whorled milkweed blooms later than other milkweeds with white flowers July thru September. The caterpillars in the greenhouse prefered this species to all others!
