In their native habitats of Mexico, specimens can grow to amazing sizes. However, in cultivation, they tend to be smaller and maintain a smaller manageable size. Mature stems will form a woody and scaly trunk, while the arms, especially at their tips retain their characteristic and attractive powder-blue color. They have widely spaced, short, sharp gray spines along their plump ribs. They do well in containers or in-ground with well-drained, loose soils. Watering should be limited to summer months while they are actively growing, with little to no watering during fall and winter.

Their pads are oval, often heart-shaped with smooth powdery-blue to blue-green color. This species of Opuntia is quite variable in size and shape throughout their native range. Pads have no spines but rather wide spaced glochids that are typically cinnamon to black, less occasionally whitish in color. As if their physical texture was not alluring enough, in the spring large, rose-like blooms appear near the tops of many of the pads that are an eye-catching, radiant shade of magenta pink. Moderate to slow growing. Plant in well-drained, unimproved rocky or sandy soils.

Engelman’s Prickly Pear is one of the most widely distributed types of cacti, which gives designers a clue to their adaptability and versatility. They have pleasantly rounded green pads covered with areoles that have white, gray to golden medium sized, sharp spines typically surrounded by brown glochids. Flower color variations are quite common along with some other physical characteristics like shape, size, and spine density, due to their naturally wide distribution. If you are observant, you can find flower colors ranging from yellow, to orange or pink. They will tolerate light filtered sun locations, but they should be planted in well-drained soils, with minimal water. Pads can be removed as needed to “prune” them for shape and size.
