Skullcap is a compact, mounding perennial native to Mexico that performs exceptionally well in hot, dry Texas landscapes. It produces small, tubular, rosy-pink flowers from spring through fall, often blooming continuously in warm climates. Its dense, rounded form and fine-textured, dark green foliage make it ideal for borders, rock gardens, low edging, and xeriscapes.
This plant thrives in full sun to light shade, and is remarkably drought-tolerant once established. It prefers well-drained, rocky or sandy soils, and is highly adapted to alkaline conditions, making it a perfect match for Central and West Texas. It is also deer-resistant and rarely troubled by pests or diseases. Skullcap typically grows 12 to 18 inches tall and wide, forming a tidy mound with minimal maintenance. When planting in groups, space 12 to 16 inches apart.
While it stays evergreen in mild winters, it may go semi-dormant or die back slightly in colder zones. In USDA Zones 7–10, it generally returns each year with little effort. Prune lightly in early spring to maintain its shape and encourage new growth. Avoid overwatering or heavy clay soils to prevent root rot.
