Glandularia aristigera, commonly known as moss verbena, is a low-growing, spreading perennial (often grown as an annual in colder climates) that typically reaches 4 to 12 inches tall while spreading 18 to 36 inches wide, forming a dense, mat-like groundcover. Its finely dissected, fern-like leaves measure approximately 1 to 2½ inches long and about ½ to 1½ inches wide, giving the plant a soft, airy texture. The creeping, branching stems can extend up to 2 to 3 feet in length, rooting occasionally where they touch the soil, which helps the plant fill in garden spaces effectively. From late spring through fall, it produces numerous rounded clusters of small, five-lobed flowers; each individual bloom measures about ½ inch across, while the full flower clusters range from 1 to 2½ inches in diameter. The blossoms are most commonly shades of purple, violet, lavender, or pink, often with a pale or white center. Its root system generally extends 6 to 12 inches deep, supporting good drought tolerance once established. This compact yet spreading growth habit makes moss verbena especially suitable for rock gardens, borders, containers, hanging baskets, and sunny slopes where cascading color is desired.
