About Selfheal
Selfheal, Prunella vulgaris, is a low-growing native perennial wildflower valued for its compact habit, pollinator appeal, and charming purple flower spikes. Also known as Heal-All, this adaptable plant brings soft color and ecological value to meadows, pollinator gardens, native plantings, lawn alternatives, herb gardens, and naturalized borders.
The Lance form is especially useful as a hardy, spreading perennial for gardeners who want a durable ground-covering wildflower that can tolerate regular garden conditions. Its short flower spikes bloom above green foliage and attract bees, butterflies, and other beneficial pollinators while being deer and rabbit resistant.
When to Plant Selfheal Seeds
Fall sowing is also a good option, especially for gardeners who prefer to let outdoor winter conditions naturally prepare the seeds for germination. Sow seeds after temperatures have cooled, allowing them to overwinter and sprout when conditions are favorable in the spring.
For spring planting, seeds may be started indoors several weeks before the last frost or sown outdoors after the danger of hard frost has passed. For best germination, seeds benefit from a period of cold moist stratification approximately four to six weeks before spring sowing.
In mild climates, fall or late winter sowing can help seedlings establish before summer heat arrives.
Where to Plant Selfheal Seeds
Choose a location with full sun to partial shade. Selfheal performs well in open sunny sites but also tolerates some shade, especially in warmer regions. Selfheal grows naturally in meadows, woodland edges, lawns, open fields, and moist grassy areas.
For visual appeal, plant Selfheal with creeping thyme, blue flax, yarrow, violet, or chamomile. These companions create a soft, natural look and help build a low, colorful planting.
How to Plant Selfheal Seeds
If planting in the spring, provide four weeks of cold moist stratification, then sow seeds about 1/8 inch deep into a seed-starting mix (for containers) or loosened weed- grass- and debris-free soil. Because the seeds need light to germinate, press them gently into the soil surface for good seed-to-soil contact and dust with a thin layer of fine soil. Keep the seedbed evenly moist during germination.
Keep trays moist and provide bright light after germination. Transplant seedlings carefully after they have developed several true leaves. Harden off young plants before moving them into the garden. A spacing of about 6 to 12 inches works well for a fuller ground cover effect, while wider spacing can be used in meadow or naturalized plantings.
How to Care for Selfheal
Once established, Selfheal prefers average moisture and can tolerate short dry periods. It performs especially well where soil stays moderately moist but drains well. Selfheal is an easy-care perennial once established.
After flowering, plants may be lightly trimmed to encourage fresh growth and maintain a tidy appearance. Deadheading can reduce self-seeding, while leaving some spent flower spikes in place may allow plants to naturalize in favorable conditions.
Selfheal can spread by seed and short creeping stems. In naturalized plantings, this is often desirable. In formal beds, trim or divide plants as needed to keep them within bounds.
