Silky Prairie Clover (Dalea villosa)

Silky Prairie Clover

Dalea villosa

Silky Prairie Clover is a low-growing, spreading perennial with fine, silvery foliage and clusters of pink to purple flowers that bloom in mid to late summer. Typically found in sandy prairies and dunes, it prefers dry, well-drained soils. Its deep root system makes it highly drought-tolerant and effective for erosion control. This species is excellent for naturalistic plantings, sandy site restorations, and pollinator gardens, where it attracts bees and butterflies.

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.
