Rose verbena (Glandularia canadensis, formerly Verbena canadensis) is an easy, long-blooming beauty, with clusters of rosy to purplish pink flowers. Here at Hayefield, it starts flowering in mid- to late April on overwintered plants or in midsummer from spring-started seedlings and continues into October. The plant usually stays around 8 to 12 inches tall but sends out long trailing stems, so it can get 1 to 2 feet wide over the growing season, or even wider if the stems take root where they touch the ground. Rose verbena thrives in full sun and can tolerate dry soil well, so it’s great for difficult sites, like slopes and curbside plantings.
Full sun (for best flowering) to light shade. Native to much of eastern North America, rose verbena is reportedly hardy in Zones 6 to 9. (It usually overwinters in my Zone 6/7 garden.) Or, you can grow it as an annual anywhere—a nice plus if you’re looking to go native in your flower beds and containers. This species is also excellent for attracting butterflies.
