Asclepias verticillata (Apocynaceae)
Threadlike leaves whorl around upright stems, with small umbels of creamy-white flowers appearing from July to September. A lovely texture plant, with unusual foliage forming an airy mass. Wonderful interplanted with species Echinaceas like E. pallida and E. paradoxa. A. verticillata is broadly distributed over much of the eastern and central US; drought tolerant and adaptable to marginal soils. Spreads by runners — give this milkweed some room to roam in more fertile soil or divide and replant established plants in spring.
