seeds of this beautiful Asclepias pumila or Plains Milkweed is one of the smallest milkweeds. Their 1/2 inch long and 1/l6 inch wide leaves usually alternate in a tight spiral up the stems. These blossom in zones 4-8 throughout July and August and will bring more butterflies than you can imagine. The gorgous rosy/gray colored blossoms are beautiful and dainty. These 8-10 inch plants are perennials and grow in full sun and sandy dry soil is best for them. Quite a drought tolerant plant
