Yuccas are very drought tolerant plants native to the dry regions of the southwestern U.S., Central and South America. A few species are found in more northern, central, and eastern parts of the U.S. Some species are considered invasive in rangelands.
Yuccas have sword like leaves and send up tall spikes with white flowers that bloom from late spring to early summer. Some species of these long-lived plants can grow up to 15 feet or more in height.
Yuccas need dry well drained soils and full sun. Depending on species, they are hardy in USDA Zones 4 to 9.
Yuccas are a great choice as an accent plant for a water-wise landscape.
