African dogtooth grass was discovered by Denver Botanic Gardens’ Panayoti Kelaidis in the early 1980's. In the late '80's, Colorado horticulturalist Kelly Grummons recognized the grass might have a use in Colorado lawns and through his extensive testing, developed Dog Tuff™. The resulting grass, Dog Tuff™ was recognized in 2015 by the trade group Direct Gardening Association and in 2016 by Plant Select. Dog Tuff™ is a warm weather grass, so the time to plant it is now as opposed to Kentucky Blue grass and Perennial Rye, which are cool weather grasses and are planted in the spring and fall. Dog Tuff™ doesn't produce seeds. In the end, Dog Tuff™ may be best used in a small, well-controlled space such as a dog run, rather than an entire lawn.
