10 Seeds Western Sand Milkweed Asclepias arenaria Native Perennial Drought Tolerant

Western Sand Milkweed (Asclepias arenaria) is a native perennial milkweed of the central and southern Great Plains, where it grows on sandy soils, dunes, and open grasslands. It forms upright stems with narrow, gray-green leaves and clusters of small greenish-white to pale pink flowers that appear in summer, followed by distinctive seed pods. Its compact, drought-adapted habit and understated flowers make it a fitting choice for native plant gardens, xeriscapes, and pollinator-friendly landscapes.
In the garden, Western Sand Milkweed works well in sandy or well-drained borders, rock gardens, and wildflower meadows, where its deep taproot and tolerance of dry conditions suit low-water plantings. The flowers produce nectar that attracts a range of insects, and the plant serves as a host for monarch and other butterflies. Allow seed pods to mature if you wish to collect seed, or leave them for winter interest. It pairs naturally with other prairie and sand-loving species.
