A large, branching columnar cactus with blue-green stems that grows into a tree-like form. In late spring it opens huge white flowers after dark, followed by red, apple-size fruit.
Living with it in the Phoenix Valley
Watering
Follow the cactus guidance in our Landscape Care guide. Established plants need only occasional summer water, if any. Well-drained soil is a must; damp, heavy soil leads to root rot.
Pruning
Not required. Remove an arm that rubs or crowds, or to control size. Cut pieces root easily after the end calluses.
Planting
Fall or early spring planting gives it time to settle in before summer heat.
Harvest
The fruit is sweet and mild. Pick it when fully colored; fallen fruit will draw birds and other wildlife.
How our designers use it
Architectural focal point
Its upright, branching form anchors a desert garden or the corner of a large yard.
Screening
Over time it can screen a side yard, utility area or neighbor’s view.
Evening gardens
Placed within view of a patio, its night blooms become an event worth staying up for.
Good to know
Around the pool
The spines are short, but fallen flowers and fruit are messy. Keep it several feet back from the water and deck.
Size
It gets big. Plan for its full height and spread rather than trimming it to fit later.
