Agave triangularis (Triangle Agave) - A slow growing medium sized agave to 2 feet tall by nearly 3 feet wide that suckers to form open clumps with olive-green triangular dagger-shaped leaves that are 18 to 24 inches long. The leaves have a pale midrib, small marginal teeth and a 1 inch terminal spine and are arranged radiating outward in the rosette in what it often referred to as a starburst affect. When drought stressed the leaves of this plant can take on reddish tones. It is know to rarely flower. Plant in well-drained soil in full sun to light shade and irrigate little to occasionally - more regular summer water speeds growth. Hardy to around 25 F. The species ranges from the Mexican states of Oaxaca and Puebla at 5,500 to 6,500 feet and is common on the calcareous mesa west of Tehuacan in Southern Puebla. Howard Scott Gentry noted in "Agaves of Continental North America" that "A. triangularis is uncommon in American gardens but once established it should endure indefinitely." Our thanks to Mountain States Nursery for providing us with this interesting plant.  The information on this page is based on our research that has been conducted on this plant in our nursery library, from online sources, and from observations made of the crops growing in the nursery, plants in the nursery's garden and those in other gardens where we have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Agave triangularis.
