Its distinctive features include small, purple-lipped flowers and the common name "Self-Heal," thought to derive from its traditional use in herbal medicine for healing wounds and ailments. With a hardiness range of 3–7, Self-Heal is well-suited for gardens and landscapes where it can grow to about 0.2 meters tall.
