Poke Milkweed

Asclepias exaltata

Asclepias exaltata, or Poke Milkweed, is a perennial plant that grows 3 to 5 feet tall. It features large, oval-shaped leaves and produces drooping clusters of white to pale pink flowers from June to August. This species is typically found in moist woodlands and forest edges, preferring rich, loamy soils. Poke Milkweed is known to attract various pollinators, including butterflies and bees, making it beneficial for wildlife gardens. In landscaping, it is valued for its tall stature and ability to thrive in shaded areas.

Sowing Information

Sow seed onto a firm, weed-free seedbed. Hand-broadcast seed making two perpendicular passes for even coverage. If planting a mix, broadcast the grass component first and lightly rake/drag it into the top 1/8–1/4" of soil. Next, broadcast wildflower/forb seed and press it into the soil surface (with a roller/cultipacker or the back of a rake) to ensure good seed-to-soil contact. After seeding, apply a very light layer of clean, seed-free straw (or other weed-free, site-appropriate mulch) to reduce erosion and retain moisture without smothering seedlings. A good rainfall or thorough watering will help settle seed and mulch and improve germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
