This evergreen yucca has a rosette of unusual blue-green leaves and tall spikes of creamy white, bell-shaped summer flowers. Performs best in full sun and is hardy in Zones 5a – 9b. Requires well drained soil and once established, can survive some drought conditions. Blue Sentry Yucca stands out in a xeriscape type setting or can be planted in large containers. Grows slowly with a mature size of 2-3’H X 2-3’S. While this plant does not have a pronounced spine tip, it is best not to plant in near close pathways or where children or pets may play. Sold here at Creekside Nursery in 5 and 15 gallon containers.
