Asclepias verticillata, or Whorled Milkweed, is a small, deer and rabbit-resistant plant with thin, "whorled" leaves and a height of around 2 feet when mature. It blooms later in the year, from July to September, producing clusters of white, sometimes greenish-white flowers that attract a wide variety of pollinators, including bees, butterflies, and beetles. This milkweed is a host plant for Monarch butterfly larvae and spreads through rhizomes, forming drifts of flowers. It thrives in well-drained, sandy or gravelly soils and prefers full sun, blending well in wildflower meadows or rock gardens. Its narrow leaves and slender seed pods provide interest throughout the seasons, though it is poisonous to livestock.
