Motherwort (Leonurus cardiaca) is a rugged, long-lived perennial valued for its dramatic height, lobed foliage, and whorled pink-lipped flowers along upright stems. A classic wildflower for naturalistic plantings, it attracts bees and beneficial insects across the growing season. Motherwort performs well with minimal care, thriving in poor soils and spreading into impressive clumps that bring height and texture to cottage gardens, meadows, wildlife areas, and ornamental borders.

Planting Guide
- Best results from cold stratification for 2–4 weeks (refrigerate seeds in moist medium).
- Sow indoors before the last frost or direct sow outdoors in late fall or early spring.
- Press seeds lightly into the soil surface or cover very thinly (1/16–1/8 inch).
- Keep soil lightly moist until germination (14–35 days).
- Transplant or thin seedlings to 12–18 inches apart.
- Choose full sun for tallest plants and strongest blooms.
- Water moderately until established; reduce watering afterward.
- Allow seedheads to mature if natural reseeding or wildlife habitat is desired.
- Remove seedheads if spread needs control.
