Peruvian Apple Cactus (Cereus repandus, syn. Cereus peruvianus)
The Peruvian Apple is a stunning centerpiece for any desert permascape. This columnar “tree cactus” produces deliciously edible fruit and truly thrives on neglect once established, making it a top candidate for desert food forests!
Mature Size
3–6 ft wide, 15–30 ft tall (often multi-stemmed, forming upright columns)
Growth Rate
Fast for a cactus — 1–2 ft per year with irrigation
Water Requirements (Minimum vs. Maximum Growth)
Minimum: Very low — thrives on rainfall once established
For Maximum Growth & Fruit: Deep watering every 2–4 weeks in summer encourages rapid height gain and heavy fruiting
Ecological & Functional Benefits
Provides striking vertical structure — living sculpture in the landscape
White, night-blooming flowers attract moths and pollinators
Fruit supports birds and desert wildlife
Excellent focal-point plant for modern or desert-style gardens
Edible / Harvest Season / Nutritional Benefits
Yes — produces sweet, mild fruit often called “Peruvian apple” or pitaya
Harvest Season: Summer through fall, depending on rainfall and irrigation
Nutrition: Hydrating, rich in vitamin C, fiber, and antioxidants
Tips for Maximizing Quality:
Harvest fruit when skin turns reddish-pink and begins to split slightly
Irrigate consistently in summer for larger, juicier fruit
Protect ripening fruit from birds with mesh bags if yields are for human harvest
Minimum Chill Hours
None — fully tropical/subtropical cactus, no winter dormancy requirement
Maintenance Requirements
Very low — occasional thinning of excess arms or trimming at base if crowding
Prune cautiously; cactus arms can be replanted as cuttings
Thorny or Not?
Yes — sharp spines along ribs
Deciduous or Not?
Evergreen — remains photosynthetic year-round
Root System
Shallow, wide-spreading fibrous roots
Non-invasive, safe near hardscape, pools, or septic systems
Benefits from well-drained soil — avoid planting in chronically wet areas
Easy to establish from cuttings due to shallow rooting nature
Native Range
Native to northern South America and the Caribbean (not the Sonoran Desert). Thrives in arid and semi-arid regions with hot summers. Widely cultivated in desert gardens worldwide.
Miscellaneous Notes
Night-blooming flowers are large, fragrant, and spectacular but short-lived
Columns can reach 30 ft, making it one of the tallest cacti suitable for landscaping
Striking as a standalone centerpiece, in rows for a “living fence,” or mixed with boulders and agaves
Extremely heat- and drought-tolerant — thrives with neglect once established
