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 cold 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, Paraguay, Uruguay 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 Verbena bonariensis var. rigida (Spreng.) Kuntze, Verbena bonariensis var. venosa (Gillies & Hook.) Chodat or Verbena bonariensis forma venosa (Gillies & Hook.) Chodat and it is sometimes listed as Glandularia rigida, but the current name according the Royal Botanic Garden Kew's database 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. We grew this plant from 2017 until 2020. 

This information about Verbena rigida displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
