- 40-60 ft tall, 20-40 ft canopy spread; massive trunk 2-3 ft in diameter
- Growth rate
- Slow to moderate
- Bloom
- Creamy yellow/orange, Spring; dioecious. Female trees bear large clusters of small orange dates (not good eating).
- Cold hardiness
- Hardy to about 15-20F; very heat- and drought-tolerant and frost-hardy for Tucson winters.
- Soil
- Tolerant of poor, sandy, and alkaline soils with good drainage; well adapted to Tucson conditions.
- Native range
- Canary Islands (off northwest Africa)
- Best used as
- Large specimen/feature palm, Estate, street, and median plantings, Mediterranean and desert landscapes
- Wildlife
- Fruit eaten by birds and mammals; flowers attract bees.
- Toxicity
- Non-toxic; fruit technically edible but poor quality. Large sharp basal spines are the main hazard and can cause serious puncture injuries.
How to grow Canary Island Date Palm in Tucson & the low desert
Watering
Drought-tolerant once established but performs best with deep, periodic irrigation; deep soak every 1-2 weeks in summer, monthly in winter, watering out to the canopy drip line. Avoid frequent shallow watering.
Fertilizer & nutrients
Apply palm fertilizer with micronutrients 2-3 times in the warm season. Prone to potassium and magnesium deficiency (frond tip necrosis) in alkaline soil; manganese deficiency causes 'frizzle top' on new growth.
Pruning & care
Remove dead lower fronds and old fruit stalks; the trimmed leaf bases form the distinctive 'pineapple' crown. Use extreme caution: basal frond spines are large and sharp, and pruning wounds can spread Fusarium wilt if tools aren't sanitized between palms.
Notes
A massive, long-lived statement palm well suited to Tucson's climate, but it needs significant space and overhead clearance and is expensive to maintain at height. Susceptible to Fusarium wilt spread by contaminated pruning tools, so disinfect equipment between palms. The very large, sharp basal spines pose a real safety risk; site away from walkways and play areas.
