The Dasylirion longissimum can survive down to -6°C in a dry winter. It is important that the grass tree is well sheltered in winter and that the soil remains as dry as possible. It is therefore important to protect this plant well against snow, hail or rain in the Dutch winters.
The Dasylirion longissimum is also called the Mexican grass tree and originates as the name implies from eastern Mexico. The Dasylirion longissimum forms its trunk in the same way as Yucca Rostrata and this tribe is characterized by its dark color. The leaf of the Dasylirion is less than half a centimeter wide but can grow up to 120 cm long. These beautiful grass trees are perfectly suitable as a tub plant and give a powerful accent to any garden. The Dasylirion longissimum is actually not a palm tree but a succulent. A beautiful feature that the Dasylirion shares with the Yucca Rostrata is a beautiful stem with flowers that grows from the core of the palm through the crown. This Mexican grass tree can grow up to 5 meters high in nature, but due to the northern European weather influences, the Dasylirion longissimum will rarely reach this height as a container plant.
