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 displayed on this page about Agave triangularis is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.

 
We closed for regular business at the end of 2025 in order for the property to be developed for affordable housing.
Our gates remain closed but we will open them by appointment to interested parties as we liquidate remaining supplies and equipment.
