- Aside from the interest provided by its lovely blossoms, Big Betony is easy to grow, naturalizes well, is pest and disease-free, deer or rabbit resistant and requires low maintenance. Its eye-catching flowers are attractive to pollinating insects.
- Its noteworthy qualities have earned it the Award of Garden Merit of the Royal Horticultural Society
- Thriving in full sun or light shade (in hot and humid areas), in average, medium moisture, and well-drained soils, this plant generally grows in a compact mound up to 18-24 in. tall and wide (45-60 cm).
- Hardy, this deciduous herbaceous perennial comes back reliably year after year. Drought tolerant once established. However, it is short-lived in the South and suffers from severe heat and humidity.
- Wonderful for edging, borders, informal naturalized spots, or cottage gardens. Big Betony also makes a fabulous ground cover for large, open, sunny garden areas. Valuable as a cut flower too! Plant in groups of 3 or more, for better visual impact. Combine Big Betony with Lady's Mantle (Alchemilla Mollis), roses, or daisies
