Glandularia canadensis (Rose Vervain) is a clumping, sprawling annual or perennial boasting abundant flat-topped clusters of up to 20 fragrant, rose-pink to rose-purple flowers from late spring to late summer. Blooming its heart out over a long season, Rose Vervain attracts butterflies and many pollinating insects. The deeply lobed dark green foliage creates a lovely foil for the showy flowers. Rose Vervain can spread quickly via ground-hugging stems rooting at the nodes where they touch the ground to form a pretty, aromatic ground cover. This plant behaves as an annual where winters are harsh, as a perennial elsewhere. Glandularia canadensis is great for rock gardens, sunny borders, landscape restorations, trailing over rock walls, or cascading from containers.

  • Grows up to 6-18 in. tall (15-45 cm) and 12-24 in. wide (30-60 cm). Will self-seed in ideal growing conditions.
  • Performs best in full sun to part shade, in average, dry to medium, well-drained soils. Excellent drainage is important. Water during dry summers to prevent leaf loss. Mulch in winter to prevent freezing to death.
  • Great candidate for borders or rock gardens and provides a stunning effect when planted en masse. Attractive as a ground cover, it is also perfect for edging, containers, or hanging baskets.
  • Easy to grow, and resilient to most pests and diseases, this low-maintenance plant is also drought, heat, dry soil, and rocky soil tolerant. Keep an eye out for powdery mildew and spider mites.
  • Propagate by root division, seed sown in spring or fall, softwood cuttings.
  • Native to the United States, from Illinois south to central Texas, west to Colorado, east to Virginia and Florida.
