HOW TO GROW MILKWEED, NARROWLEAF
Direct sow in the fall or sow indoors 8 weeks before last frost. If you sow indoors, cold stratify the seeds for 12 weeks in the refrigerator before planting. Sow seeds 1/2” deep. If direct sowing, space seeds 4-6” apart, and plant transplants 3’-4’ apart. Keep seeds evenly moist when germinating, and water only periodically in the summer as plants are drought tolerant and grow deep taproots. Hardiness zones 6-10. Perennial.

Narrowleaf Milkweed is the sole source of food for Monarch butterflies. The butterflies lay their eggs exclusively on Milkweed plants. The plants grow 2-4’ tall and attract other pollinators as well with their deliciously fragrant flowers that bloom from June through September. This perennial may not bloom in its first year, but after establishing a deep taproot to ensure survival in drought conditions, it will grow more vigorous and blossom in subsequent seasons. If the greenish/whitish whorled leaves appear eaten, it’s a good sign that monarch caterpillars are eating! Harvest seed pods before they split open. Prune the plant back to a 1” stick in the fall to encourage winter dormancy. Tags: Harvest: Mid, Color: Pink, Size: Medium, Specialty: Drought Tolerant, Season: Late Spring, Summer.
