Mexican Grass Tree

Dasylirion longissimum (Mexican Grass Tree) Many horticulturists would consider this to be quite a stunning plant. It needs lots of room to grow. It forms a dome of blue-green leaves that have an unusual swaying movement in just the slightest breeze. It grows to 4-6′ wide. If the leaves are cut back to keep it smaller the normal shape is marred. Both male & female plants have very tall flower stalks that reach 6-10′. Female flowers turn a lovely russet color as they mature. Dasylirion longissimum blooms in late winter. After several years (up to 50 or so) it will start to develop a trunk. It can be grown in a pot for quite some time but eventually must be planted in the ground. In fire prone areas it is considered fire-retardant. This native of Mexico requires good soil drainage.
