Description
A spreading, low pricklypear with flattened pads, showy flowers, and a variable look depending on site and season. Pads can form broad clumps close to the ground, and the plants often read as a defensive mat more than an upright cactus. Flower color varies, but the growth form is the first clue.
Wildlife & pollinators
Flowers feed bees; fruits and pads are used by birds and small mammals. Cactus clumps also provide cover.
Habitat & range
Cold-desert and high-desert country across the Great Basin and interior West, including sagebrush and east-side mountain-edge habitats around the 395 corridor.
In the garden
A strong choice for true dry, cold, sunny landscapes where you want a tough native cactus. Needs excellent drainage and some respect for its spines.
Propagation
From pad cuttings or seed. Let detached pads callus before setting them on dry mineral soil.
