Dasylirion longissimum
Mexican Grass Tree
Description
Mexican Grass Tree requires little maintenance and is popular in desert-themed gardens. Plants tolerate drought, reflected heat and poor soils. It slowly develops a short, thick trunk while reaching 6' tall and wide. Leaves are very narrow and long making it more hair-like than the other Dasylirions. They are 3' long, and gray-green with thorns on the tips. During late spring to summer, an erect stem of white creamy flowers emerge from the center, up to 10' high. This long-lived plant needs well draining soil. Do not plant near walkways.
