Asclepias verticillata is an upright plant with very narrow, needle-like leaves on unbranched stems. It forms clusters of fragrant white blooms that are held in the upper leaf axils and on stem ends. Commonly referred to as Whorled Milkweed, this perennial plant is rhizomatous and will spread. Whorled Milkweed is native to the eastern two thirds of North America. Asclepias verticillata is a host to Monarch caterpillars and it also makes a good nectar source.
* As of June 1st these plants have been treated with a systemic pesticide in accordance with the USDA required Japanese Beetle Harmonization Plan. The pesticide is not a neonicotinoid, but if you plan on hosting any insects or insect larvae with these plants please keep them quarantined for at least 3 weeks. This will give the systemic pesticide sufficient time to move through the plant’s root and foliar system, after which they will be safe host plants.
