About Shrubby St. John's Wort, Hypericum Seed
Shrubby St. John's Wort (Hypericum prolificum) is a distinctive North American native plant. This well-behaved native shrub forms a rounded habit and covers itself with bright yellow flowers that are especially attractive to bumblebees. It matures at approximately 48 inches tall and flowers from early to mid summer through mid to late summer. Plant it in full sun to partial shade, in dry-medium through medium-wet conditions, with loamy soil, clay soil, sandy soil or poor soil. Space plants 36–48 inches apart for healthy growth and airflow.

Tips
Pests & Diseases
Provide suitable spacing and airflow, water near the soil surface, and remove heavily affected debris if leaf spots, mildew, or stem decline appear. Avoid keeping crowns continuously saturated unless the species requires wet conditions.
Inspect seedlings and young growth for slugs, chewing insects, and sap-feeding pests. Healthy established native plants often tolerate light feeding; identify the pest before using the least disruptive labeled control.
