Origin: Desert mountain and montane regions within pinyon/juniper woodlands, desert scrub edges, chaparral of western Arizona, southern California, and southern Nevada south into northern Mexico.

Pronounciation: O-PUN-tee-a chlo-ro-TEE-ka

Hardiness zones:
Sunset 2-3, 10-12, 18-23
USDA 6-10

Landscape Use: Cactus rock gardens, textural accent for small to medium sized high elevation desert landscape areas.

Character: Much branched individual stems upright, stiff, spreading, imposing.

Growth Habit: Moderately slow, arborescent, densely branched, branches ascending with round branch segments to 4 feet in height.

Foliage/texture: Stems are jointed into fleshy, round clades (padded stems) that are lighter green with occassionally slightly yellowed hue, 3 to 8 spines per aeroles, spines are generally 2 to 3 inches in length, straight, glochids and spines are transluscent golden yellow in color; coarse texture.

Temperature: Cold tolerant to 10oF. Heat tolerant to 110oF.

Light: Full sun

Soil: Tolerant

Watering: None after established.

Pruning: Prune by removing pad segments of any length to control spread, keep an open appearance, and inhibit prospects of cochineal scale.

Propagation: Cutting and dispersal of pads.

Disease and pests: Root rot and cochineal scale.

Additional comments: Pancake prickly pear is a cactus for xeric landscapes in mid to high elevation towns and cities of Arizona such as Prescott, Payson, and Sierra Vista. It can be cultivated in Tucson with some protection from intense western exposures, but cultivation in Phoenix and other low elevation desert landscape is difficult due to the extreme summer heat.
