Mexican Grass Tree

Dasylirion longissimum

Stiff, spineless, olive green, grass-like foliage flows from the center of this perfect evergreen specimen for warm, arid xeriscapes. Remove old foliage to reveal an attractive single trunk. In time, it will produce a single, magnificent, tall white bloom stalk. A captivating feature in raised planters and large containers.
