Mexican Grass Tree is neither a grass nor a tree, but that doesn’t detract from its superb qualities for landscaping. Stiff but arching grass-like foliage seems to flow out of the center of this tidy, sculptural succulent related to agaves and nolinas. Besides being prized for its easy care and low water use, Mexican Grass Tree is captivating as a living kinetic “sculpture”, serving as yard art whenever breezes animate its numerous 4-foot-long leaves. Its large woody trunk grows very slowly to 6-10 feet tall, and in late spring to summer, both male and female plants produce a 9-foot-tall spike of small creamy flowers. This spectacular accent plant asks only for good drainage (it hates soggy soil), and some protection from harsh afternoon sun in extremely hot regions. A beautiful accent or specimen plant, but also useful in rock gardens, as a border, or in mass plantings. It is stunning in raised planters or large containers.
