Name: Narrowleaf Milkweed (Asclepias Fascicularis)
Description: 3ft tall clumps of stalks with long, narrow leaves and dense clusters of pinkish white flowers at the end. Clusters of established plants can resemble a shrub.
Type: Perennial. Regrows from root.
Ideal Zone: 8+ but will grow as an annual below that.
Sun: Full sun to part shade. Able to grow in desert climates.
Soil Conditions: Will tolerate a wide variety of soil conditions, even clay and sand.
Water Requirement: Low, once established. Can survive arid periods. Will require slightly more if planted in pots. Tolerates occasional flooding.
Growing Instructions: In Northern climates, sow seeds indoors 2 months before final frost to allow plants to reach full maturity. Warmer climates can sow directly outdoors after final frost. Plant 2-3ft apart , ¼ to ½” below the soil surface. Soaking seeds in warm water 24 hours before planting may assist gemination. Can be planted directly in the ground or in pots or planters. If using a seed tray, move plants to final location when seedlings reach 2-3” tall to avoid binding roots.
Growing Notes: Under ideal conditions, these plants will produce many seeds and propagate easily. Put a rubber band around seed pods to prevent them from opening if you want the seeds for later use or pinch them off to prevent reseeding altogether. Stem cuttings will re-root in water or moist soil in warm weather. Plants die back in fall/winter but will regrow from root and seed the following year.
In the Garden: A host plant for Monarch and Queen butterflies. Native to California and Southwestern US. Large numbers of caterpillars will strip the plants to bare stems, but the leaves grow back quickly. Established plants can be dense and able to support many caterpillars. All types of butterflies will love the nectar produced by the flowers. The milky sap is a mild irritant, which makes the butterflies distasteful to predators. Can be prone to aphids, but this does not seem to damage the plant.
