Purple Milkweed

Purple Milkweed (Asclepias purpurascens)

Purple Milkweed (Asclepias purpurascens) is a striking native perennial known for its rich, deep purple flower clusters and its critical role in supporting pollinators. As a host plant for monarch butterflies, this beautiful wildflower is an essential addition to pollinator gardens, meadows, and naturalized landscapes.

Distinctive Features

Purple Milkweed produces upright stems with broad, lance-shaped green leaves and topped with dense, fragrant purple flower clusters that bloom from late spring to early summer. Similar in structure to Common Milkweed but with darker, more vibrant blooms, this species provides a dramatic visual impact while supporting various butterfly and bee species. In fall, its seed pods open to release silky seeds that are dispersed by the wind.

• Soil: Prefers well-draining, loamy or sandy soil; tolerates average to dry conditions.
• Water: Moderate water needs; drought-tolerant once established.
• Humidity: Prefers moderate humidity; thrives in open, well-ventilated areas.
• USDA Hardiness Zones: 3-8, adaptable to various temperate climates.

Ideal Uses
