Dasylirion longissimum (D. quadrangulatum)(D. longissima)
The Mexican Grass Tree adds beauty and texture to the landscape with its numerous, long, narrow leaves that shimmer in the breeze and the light.
Dasylirion longissimum may look like a large grass but the very thin, grey-green leaves are rigid and long, measuring 4-6 ft. by ¼ inch wide. The wiry leaves radiate outward from the crown symmetrically, creating a finely textured, sculptural appearance that fits perfectly in a mid-century modern garden design, desert garden, or even a formal garden. Exceptional in either xeric or tropical landscapes, this amazing accent plant is also mesmerizing in containers.
Over time, Dasylirion longissimum will slowly develop a large woody trunk that reaches 10 ft. tall with a 6-8 ft. crown. Creamy white flowers on 10 ft. tall flower spikes appear on older, mature plants in summer but may not flower every year.
The Mexican Grass Tree is a long-lived, dense-leaved, evergreen succulent that tolerates heat and drought and requires little maintenance, just be sure to plant with enough space for it to reach its full size.
Add grace and symmetry to your garden today with Dasylirion longissimum. The architectural appeal of this fascinating, finely textured Mexican Grass Tree is sure to be a favorite in your landscape.
Dasylirion longissimum is best grown in loose, well-draining soil. Be sure to deeply water the soil to develop a good root system, allowing the soil to dry in between waterings; reduce frequency once established. Avoid watering the crown which can lead to rot. Give little to no water during winter as the seasonal rains may provide sufficient moisture. Mexican Grass Tree does not tolerate soggy conditions.
Plant in full sun, away from pathways to avoid encounters with the rigid leaves, and allow sufficient space around your Mexican Grass Tree to grow to full size. In extremely hot regions, Dasylirion longissimum may grow better with some light afternoon shade. The Mexican Grass Tree requires very little maintenance. Remove the dead, bottom leaves with pruners for a tidy appearance.
