Wood Betony (Pedicularis canadensis)

Wood Betony

Pedicularis canadensis

Wood Betony is a low-growing perennial that reaches about 4 to 16 inches in height. It produces distinctive yellow to reddish-purple flowers in dense spikes during late spring. This species is commonly found in prairies, oak savannas, and open woodlands, preferring well-drained soils. Wood Betony is a hemiparasitic plant, drawing nutrients from nearby grasses, which can help reduce competition from aggressive species. It is often used in prairie restorations and pollinator-friendly gardens.

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.
