One of the most durable and underrated of the Asclepias genus. The fragrance of the flowers alone makes this one of the must-haves for a garden that can spare a little space, not to mention that it seems to be one o ... f the most visited by our favorite pollinators and other insects. It can handle bad soil conditions of all types as long as it is not too wet. We recommend that you plant only a handful at most because it may “run” on the unsuspecting gardener. Host for the Monarch caterpillar as well as many other pollinators.
