Description
Narrowleaf milkweed spreads by rhizome, sending up many flowering stems with narrow, whorled leaves, topped by pinkish flower clusters. It is adaptable to many soil types, including clay soil. An important larval host plant for the monarch butterfly, but loved by many other pollinators as well. Easy to grow, deer resistant and drought tolerant. A great plant to grow for monarch butterfly habitat. Give plenty of space for this species to spread by rhizome. Drip irrigation is preferred in order to prevent leaf spot from overhead irrigation. If you plant it, it is likely monarch butterflies will find it!
Narrowleaf milkweed (Asclepias fascicularis) seed packets contain approximately 115 seeds.
Seed Germination Instructions
30-60 days of cold-moist stratification is recommended. Sow seeds outside in fall to early spring and let nature do the stratification naturally outside, if you have cold enough winters. If you live in an area with mild winters, you may need to provide the cold-moist stratification artificially. For more information please read through the information in our Seed Germination and Propagation Reference Guide.
