Summary

Glandularia canadensis, commonly known as Rose Mock Vervain, is a semi-deciduous perennial herb that thrives in prairies, open woodlands, and along roadsides in the South Central and Southeastern USA. It typically grows to a height of 0.5-2 feet (0.2-0.6 meters) and spreads 1-2 feet (0.3-0.6 meters) wide. The plant forms a low mound of foliage, with flowers that are particularly showy, presenting hues of pink, purple, and red during the spring and summer months. The blooms are comprised of five petals and are borne in dense clusters atop the foliage, offering a long-lasting display. Leaves are semi-evergreen, opposite, and pinnately-lobed, contributing to the plant’s textured appearance.

Rose Mock Vervain is valued for its extended flowering period and its ability to attract pollinators such as butterflies. It is often used in butterfly gardens, as ground cover, or in borders due to its low maintenance and drought tolerance once established. For optimal growth, it prefers full sun exposure and well-drained soils. While it tolerates low water conditions, moderate watering will encourage more vigorous growth and flowering. This species is generally disease-resistant but can be susceptible to root rot in poorly drained soils. It is not known to be invasive and does not have aggressive roots, making it a safe choice for various garden settings.CC BY-SA 4.0
