Narrow-leaved milkweed (Asclepias fascicularis) is a perennial wildflower native to western North America, including California, Oregon, Nevada, and Arizona. It typically grows 2 to 4 feet tall and features long, narrow leaves arranged in whorls along its slender stems. In summer, it produces clusters of pale pink, white, or lavender flowers that attract a variety of pollinators. After flowering, the plant forms pod-like fruits that release seeds with silky tufts for wind dispersal.
 
This milkweed thrives in USDA zones 6-10 and adapts to various habitats, including grasslands, open woodlands, and roadsides. It prefers full sun and well-drained soils but tolerates clay, sandy, and rocky substrates. Drought-tolerant once established, it benefits from occasional deep watering during prolonged dry periods. The plant goes dormant in winter and reseeds naturally, making it a low-maintenance addition to native and pollinator gardens.
 
Narrow-leaved milkweed is ecologically significant as a critical host plant for monarch butterflies, whose caterpillars feed exclusively on its leaves. Its nectar-rich flowers also attract bees, butterflies, and beneficial insects. In addition to supporting wildlife, it contributes to habitat restoration and soil stabilization. Planting narrow-leaved milkweed helps combat the decline of monarch populations while adding beauty and ecological value to any garden or landscape.
