Narrowleaf / Mexican Whorled Milkweed (Asclepias fascicularis) is a beautiful Western native prized for its slender, whorled foliage and clusters of delicate pink, white, and lavender-tinged flowers. Native to much of California and portions of Nevada and Utah, it is an excellent choice for dry Western landscapes, native plant gardens, pollinator gardens, and wildlife habitats within its natural range. Mature plants typically reach 2–4 feet tall and 1–2 feet wide, forming an attractive, upright clump. Best suited to USDA Zones 6–10, it thrives in full sun and well-draining soil and is well adapted to dry conditions once established. Established plants can tolerate summer temperatures around 95–110°F and cold temperatures near -10 to 0°F, depending on conditions and local ecotype. In colder climates, the plant may die back to the ground during winter and regrow in spring. Water regularly while establishing, then reduce watering once established.
Stratification & Germination: Asclepias fascicularis seeds can benefit from cold, moist stratification, which helps break seed dormancy and can improve germination. For best results, place seeds in a lightly moistened medium and refrigerate them for approximately 30 days before sowing. After stratification, sow the seeds on the surface of a well-draining seed-starting mix and press them gently into the soil rather than covering them deeply, as milkweed seeds need light to germinate. Keep the medium evenly moist but not saturated and provide warmth and bright light. Germination can be somewhat irregular, so allow several weeks for seedlings to emerge and avoid discarding seed trays too early. Fresh seed generally provides the best germination, and seedlings should be transplanted carefully once they are well established.
Milkweed contains toxic cardiac glycosides and should be kept away from pets, livestock, and children.
