Verbena rigida (Sand Paper Verbena) - An evergreen perennial to 1 to 2 feet tall and spreading wider from underground by rhizomes. It has rough textured 2 to 3 inch long dark green leaves that have sharp points on the well-spaced lobes along the leaf margin and on leaf tip and small vivid purple fragrant flowers held in tight cluster on branching panicles from spring through fall - can bloom into winter in mild climates. Plant in full sun (best) or in partial shade in a well drained soil. Tolerates heat and dry conditions but also more regular irrigation and is hardy to 0 °F and useful as a long blooming annual in even colder locations. Cut back hard to the ground after flowering or when looking haggard and it will quickly resprout. Has been a little pesky in some locations as it will spread wide if allowed and has been known to reseed in the garden. The flowers are attractive to hummingbirds and butterflies, but the rough foliage is resistant to predation by deer. This plant is native to Brazil, Bolivia and Argentina. It was first described by German botanist Kurt Polycarp Joachim Sprengel in Systema Vegetabilium in 1827 and others have proposed it be included with Verbena bonariensis as V. bonariensis var. rigida (Spreng.) Kuntze or V. bonariensis var. venosa (Gillies & Hook.) Chodat and it is sometimes listed as Glandularia rigida, but the current name according to The Plant List (collaboration between Kew and MOBOT) remains Verbena rigida. It has also gone under the common names Prairie Verbena, Stiff Verbena, Upright Verbena, Tuberous Vervain, Slender Vervain and Hardy Garden Verbena. In England, where it typically is called the Hardy Garden Verbena it received the Royal Horticultural Society's Award of Garden Merit in 1993.
The information about Verbena rigida displayed on this page is based on research conducted in our nursery library and from online sources we consider reliable. We will also relate those observations made of this plant as it grows in our nursery gardens and in other gardens that we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone who has additional information, particularly when they share cultural information that would aid others in growing it.
