Mexican grass tree

Dasylirion quadrangulatum


The Mexican grass tree is the largest growing species of Dasylirion in cultivation. It is a natural specimen and focal accent plant due to its very long and cylindrical foliage and tall flowers spikes. A stout trunk can develop over many years and eventually reach 8-10 ft. in height; some specimens will develop branched trunks.

Mexican grass tree is native to dry hillsides and seasonal stream habitats in northeastern Mexico where it is adapted to heat, drought and winter temperatures to 15°F. It has increasingly become a popular feature and specimen plant in Inland Empire gardens. Sometimes it is planted in large containers and displayed in courtyards; other times it is part of a cacti and succulent display in southwestern and Mediterranean style gardens.
