The Mexican Grass tree is a stylish and original plant used in many modern, contemporary British gardens. With a very low trunk, the Mexican Grass Trees thin, grass-like leaves explode from the top in a neat, green tuft. Some specimen versions of this plant are cultivated so as to train the leaves into an even ball shape, dry ends creating a shimmering effect towards the edge. This plant originates from the Chihuahuan Desert overlapping the USA-Mexico border and as such is resistant to drought and extreme weather conditions. However, in order to encourage growth and good health, try and place your Dasylirion longissimum in a well drained, highly sunned position. We estimate that the recommended hardiness rating for this plant is at H3 so whilst it can survive certain cold weather conditions, it would be best to shelter. There are no known diseases that affect this plant but there are potential pests. No pruning is required. The final height of the plant is between 2.4 m – 3 m (8 ft – 10 ft) and the final width is between 1.8 m – 3.6 m (6 ft – 12 ft)
