Yucca plants with advancing age can grow into trees and some specimens have been dated to grow to more than one thousand years old in the arid deserts of the Western United States and Mexico. The yucca plant is a xericape evergreen plant that grows as a native tree in the tough environment of the desert.
Yucca plants when grown outside as specimens in the landscape, require no attention or applications of fertilizers or water. The thick leaves are prickly and resistant to drought and cold, most yuccas are cold hardy to zone 5 and 6. In the US yucca trees grow from Texas up to Virginia, and many gardeners now are experimentally planting them successfully further North in States as cold as Massachusetts, New York and New Jersey, where they have survived during the past few years.
Yucca has lance-shaped leaves growing in a rosette pattern, on a woody stem or trunk-like frame
Spanish Bayonet Yucca
The Yucca treculeana is often called the Spanish Bayonet or Spanish Dagger. Whenl it reaches the huge size that is filmed here, and when the trunk reaches 5 or 6 feet in height it forks into frightful, multiple branches. Beware of these plants, if children are nearby, and even adults dread the sting of its piercing pricks.
Red Yucca
The Red Yucca is an outstanding plant, more for its continuous, dramatic flowering and definitely more desirable than the mother plant foliage that freely multiplies by offsetting to form babies. The tall red spikes of flowers seem to endlessly rise from the plant center at the base. This yucca is truly a rare collectors plant dream, one that is cold hardy in zones 8, 9 and 10 and absolutely perfect for containerizing.
