Estimated Native Range
Summary
Asclepias michauxii, commonly known as Michaux’s Milkweed or Sandhill Milkweed, is a perennial herb that is native to the Southeastern United States, particularly thriving in the longleaf pine savannas and sandhills, as well as in the coastal plains. It typically grows at a moderate rate to a height of 1.5-3 feet (0.46-0.9 meters) and a width of 1-1.5 feet (0.3-0.5 meters). This species is characterized by its upright stems and narrow, lanceolate leaves, with clusters of greenish-white to cream-colored flowers that bloom in the summer and are quite attractive to pollinators, especially butterflies.
Michaux’s Milkweed is valued for its role in supporting butterfly populations, including being a host plant for the Monarch butterfly larvae. It is used in native plant gardens, pollinator gardens, and restoration projects. It is adapted to dry, well-drained conditions and is quite drought-tolerant once established, making it a low-maintenance choice for gardeners. While it prefers full sun, it can tolerate part shade, especially in the hotter regions of its range. It is not commonly affected by diseases or pests, but gardeners should be aware that it can be toxic to livestock if ingested. Asclepias michauxii is not known for being invasive and is considered a beneficial native plant.CC BY-SA 4.0
