How tall and wide does Dasylirion longissimum grow to be? My belief is that it is an evergreen grass-like plant and not a perennial. Am I correct? The blades appear to be more stiff than a typical grass. I am in USDA Zone 9 and would like to know if it grows well here. |
Dasylirion longissima (D. quadrangulatum) is also called the Mexican Grss Tree. The green leaves grow in a fountainlike clump, reaching about 5 feet high and wide. It is native to the deserts and mountains of the Southwest and Mexico and produces clumps of narrow, grassy leaves which spring from a woody base that can, with age, grow into a treelike trunk. It needs good drainage and is very drought tolerant. it should be a perennial in your southern California garden. |
