Texas sotol

Sun

Full sun; tolerates light shade but develops its best shape in strong light.

Water

Low once established. Water young plants during dry spells, allowing the soil to dry between waterings; established plants rarely need irrigation outside prolonged drought.

Soil

Sharply drained sandy, gritty or rocky soil, including limestone soils. Avoid wet clay and sites that stay damp in winter.

Height

3-5 ft (0.9-1.5 m) in leaf; flower stalks can reach 10-15 ft (3-4.6 m)

Spread

3-5 ft (0.9-1.5 m)

Flowers

Late spring to summer; small creamy-white to greenish-white flowers packed along tall stalks. Mature plants do not necessarily flower every year.

Foliage

Evergreen. Narrow, firm green leaves arch outward from a dense rosette, with small hooked teeth along their edges and fibrous tips.

Slow

Growth rate

Slow

• Plant after the risk of hard frost has passed, keeping the crown at its original soil level.
• Water deeply during establishment, then let the root zone dry before watering again.
• Use a raised bed or a free-draining container where winter rainfall is heavy.
• Apply gravel mulch rather than moisture-holding organic mulch, keeping the crown clear.
• Avoid routine feeding; rich soil and excess fertiliser are unnecessary.
• Wear thick gloves, long sleeves and eye protection when working among the leaves.

Pruning. In spring, cut away fully dead or badly damaged leaves near their bases without cutting into the crown. Remove spent flower stalks near the base when dry, and do not shear or shorten healthy leaves.

Spring

Remove winter-damaged leaves and check that the crown is firm and drainage remains clear.

Late spring

Plant once the soil has warmed and hard frosts have passed.

Summer

Water recently planted specimens during dry spells, letting the soil dry between soakings.

Late summer

Leave flower stalks for seed or cut them down once they have dried.

Autumn

Clear fallen leaves from the crown and stop supplementary watering as conditions cool.

Winter

Keep container plants sheltered from persistent rain and protect them from severe freezes.

• Use a single plant as a focal point in a sunny gravel courtyard, well back from seating and paths.
• Repeat widely spaced plants among rocks and low groundcovers for a restrained architectural planting.
• Combine with agaves, yuccas and drought-tolerant grasses in a southwestern dry garden.
• Grow in a large, free-draining container to display its fountain-shaped foliage.

Garden styles it suits: Architectural minimal, Desert modern, Dry gravel garden, Desert / xeriscape, Southwestern and Texas Hill Country.

Plant it with: Red yucca, Texas sage, Blackfoot daisy, Autumn sage, Blue grama and Parry's agave.

Wildlife: Flowers provide food for bees and other insects. Male and female flowers occur on separate plants, so seed production requires both sexes nearby. The dense foliage can shelter small wildlife.

• Root or crown rot in wet soil: improve drainage, keep mulch away from the crown and avoid winter irrigation; badly rotted plants may not recover.
• Freeze damage, especially in damp conditions: choose a sheltered, sunny site and protect container roots during severe cold; remove dead foliage in spring.
• Poor shape or weak growth in shade: move young plants to a sunnier position rather than trying to correct growth with fertiliser.

Not known to be toxic to people, cats, dogs or horses, although species-specific toxicity information is limited. The main hazard is physical: the toothed leaves can cut skin and injure eyes or mouths. Do not treat it as an edible garden plant.

• Desert spoon (Dasylirion wheeleri)

  Usually has distinctly blue-grey leaves, while Texas sotol is generally green; both have toothed leaf margins.

• Mexican grass tree (Dasylirion longissimum)

  Has much narrower, almost wire-like leaves with essentially smooth margins, rather than the flat, toothed leaves of Texas sotol.

• Red yucca (Hesperaloe parviflora)

  Has thread-like fibres along its leaf margins instead of hooked teeth, and usually bears coral-red tubular flowers on branching stalks.

Dasylirion comes from Greek words meaning 'shaggy lily', referring to the fibrous leaf bases, while texanum means 'of Texas'.

Propagation. Usually grown from seed sown in a warm place in a gritty, free-draining mix. Growth is slow, and seedlings take years to become substantial landscape plants. This is not a plant for routine division.
