Glandularia canadensis
Glandularia canadensis, commonly known as rose verbena, clump verbena, or rose vervain, is a native perennial plant of Texas. It typically grows in prairies, fields, pastures, rocky meadows, and roadsides. This clumping, sprawling plant can reach 6 to 18 inches and spread rapidly through its pubescent, decumbent stems, which root at the nodes when they touch the ground, creating an attractive ground cover.
Glandularia canadensis produces flat-topped clusters of rose-pink to rose-purple flowers atop upright stems from late spring to late summer. Its deeply lobed, dark green leaves have triangular bases.
For many years, this plant was classified as Verbena canadensis, and some respected authorities, such as The Royal Horticultural Society, still list it under that name. However, the revised edition of Steyermark's Flora of Missouri (by Yatskievych and Turner) now recognizes it as Glandularia canadensis. Many experts consider Glandularia to be a separate and distinct genus from Verbena based on various factors, including plant morphology, chromosome number, style length, reproductive modes, and ploidal levels (refer to Umber's work, "The Genus Glandularia (Verbenaceae) in North America," published in 1979).
Easily grown in average, dry to medium, well-drained soils in full sun. Avoid wet, poorly drained soils. Self-seeds in optimum growing conditions.
