Flowering Spurge (Euphorbia corollata)

Flowering Spurge

Euphorbia corollata

Flowering Spurge is an herbaceous perennial that grows up to 12 to 40 inches tall, with smooth stems and light green leaves arranged alternately or in whorls. Each stem terminates in a panicle of small, white flowers that bloom from June to September. It is commonly found in prairies, pastures, open woods, and along roads and train tracks, thriving in well-drained soils and exhibiting excellent drought tolerance due to its deep taproot. The plant's milky sap can cause skin and eye irritation in some individuals. In landscapes, it is suitable for dry, sunny areas, prairie restorations, and naturalized plantings, providing nectar for various pollinators.

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.
