Glandularia canadensis (Rose vervain)
Cressler, Alan
Rose vervain is a creeping annual or perennial, rooting at the nodes to form large, dense mats 5-10 in. high. Clusters of fragrant, rose-pink, five-petaled, tubular flowers occur at branch tips. The leaves may be hairy and are deeply toothed. This showy vervain is especially good for rock gardens; although it is a southern species, it is tolerant of northern climates. The somewhat similar Purple Prairie Verbena (G. bipinnatifida) has a bristly-hairy stem and finely divided leaves with stiff hairs; it occurs in fields and along sandy roadsides in Quebec and from South Dakota and Wisconsin south to Florida and Texas. Stiff Vervain (Verbena rigida), with toothed, lanceolate leaves and a more elongated flower cluster, occurs from Virginia south to Florida and west to Texas and Oklahoma.

This species is a member of the verbena family (family Verbenaceae), which includes about 75 genera and 3,000 species of herbs, shrubs, and trees, mostly of tropical and warm temperate regions. Among them, teak is a highly prized furniture wood, and Vervain, Lantana, Lippia or Frog Fruit, and Chaste Tree or Vitex are grown as ornamentals.
