This cactus will slowly grow 20-50' tall. It has long white hairs and yellow spines. Only plants over 15' tall will bloom; it produces rose colored flowers that bloom at night.

Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.
