Desert Spoon (Sotol) (Dasylirion wheeleri) is a low-water accent native to the Sonoran Desert region well suited to Tucson and the low desert.
Desert Spoon (Sotol) at a glance
- Water use
- Low (established)
- Sun
- Full sun with reflected heat; tolerates light shade. Best form and density in full sun.
- Mature size
- 3-5 ft H x 4-6 ft W rosette; flower stalk shoots up to 9-15 ft tall.
- Growth rate
- Slow.
- Bloom
- Small creamy-white to tan/straw flowers densely packed along a tall plume-like stalk; plants are dioecious (separate male and female plants)., Late spring into summer (roughly May-July); the dried tan flower spike persists into winter.
- Cold hardiness
- Cold hardy to about 0°F (USDA zone 6); fully hardy throughout the Tucson basin.
- Soil
- Well-drained rocky, gravelly, or sandy desert soils; tolerates caliche and alkaline soils. Needs good drainage.
- Native range
- Native to the Sonoran and Chihuahuan deserts and desert grasslands/uplands of southern Arizona, New Mexico, west Texas, and northern Mexico (roughly 2,000-6,000 ft); native to Arizona.
- Best used as
- Symmetrical fountain-form accent/specimen, Mid-height structure in xeriscape and rock gardens, Median, commercial, and reflected-heat plantings, Native and habitat gardens, Mass plantings for texture
- Wildlife
- Flowers attract bees and other pollinators; seeds eaten by birds and small mammals. Historically used by Indigenous peoples for fiber, food (roasted heart), and the fermented drink 'sotol'; the spoon-shaped leaf bases are used in crafts.
- Toxicity
- Not significantly toxic; no major poisoning concern for people or pets. Hazard is mechanical: leaf margins bear fine saw-like teeth that can cut, so site away from high-traffic edges.
How to grow Desert Spoon (Sotol) in Tucson & the low desert
Watering
Drought tolerant once established but looks best with a deep soak about once a month in summer; little to no supplemental water needed in cooler months. Some summer irrigation keeps the rosette full and green, but avoid overwatering and standing water.
Fertilizer & nutrients
Generally none needed in desert soils. An optional light spring application of slow-release fertilizer can be used on young plants to speed establishment; mature plants thrive unfertilized.
Pruning & care
Very low maintenance. Remove the old flower stalk after it dries (or leave for winter interest) and trim dead outer leaves. Do not shear the rosette. Leaf margins carry small, recurved teeth, so wear gloves.
Notes
Forms a dense, symmetrical fountain-like rosette of narrow, blue-green to gray-green leaves whose margins are lined with small teeth; the leaf bases broaden into a 'spoon' shape, giving the common name. A true Sonoran/Chihuahuan native that reads softer than the spiky yuccas while providing strong architectural form. Dioecious, so flower display varies by plant sex.
