Narrowleaf Milkweed (Asclepias fascicularis) is western native species with light pink flower clusters and narrow leaves. A host plant for Monarch populations on the West Coast and Great Basin, this ornamental species is easy to grow and thrives in a wide range of growing conditions. It is also a nectar source for many species of butterflies.

Seeds germinate easily with no cold stratification. Soak the seeds in warm water for about 8 hours before planting to improve germination. Place the seeds on the surface of the soil and lightly cover with soil or coconut coir. Keep the soil moist but not overly wet. Seeds typically sprout in 2-3 weeks, depending on temperature and moisture. These seeds can be fall planted, started indoors before the last frost, or started outdoors in the spring after the last frost.
