Right plant, right place

Will Desert willow grow at your Arizona property?

Excellent in a broad basin or wash receiving periodic runoff. Leave room for a multi-trunk habit and choose a low-seed selection near paving.

Best regional fit: Urban core · USDA 9b–10a, Valley suburbs · USDA 9a–9b, Desert outskirts · USDA 8b–9b, High desert · USDA 6a–8b.

Light

Sun exposure

Full sun for the strongest flowering and structure.

Water

Irrigation

Low. Deep irrigation every 10–14 days during summer supports flowering; established trees also tolerate much drier conditions.

Choose the actual plant, not only the label

Cultivars & selections

Flower color, seed-pod production, mature size, and growth habit vary materially by cultivar. Named selections are worthwhile near patios and small gardens.

Bubba

Chilopsis linearis ‘Bubba’

Mature size20–30 ft tall × 15–25 ft wide

Best forVigorous shade and dark burgundy-pink flowers

A robust landscape selection with broader leaves, heavy bloom, and generally fewer pods than seed-grown forms.

Burgundy

Chilopsis linearis ‘Burgundy’

Mature size15–25 ft tall × 10–20 ft wide

Best forDeep burgundy flower color

Selected primarily for saturated flowers; maintain a natural multi-trunk structure and confirm local availability.

Lucretia Hamilton

Chilopsis linearis ‘Lucretia Hamilton’

Mature size12–18 ft tall × 10–15 ft wide

Best forSmaller gardens and rich purple-pink flowers

More compact than many desert willows and useful where a full 25-ft canopy is too large.

Art’s Seedless

Chilopsis linearis ‘Art’s Seedless’

Mature size15–25 ft tall × 10–20 ft wide

Best forPatios and paths where litter matters

Chosen for reduced pod production while retaining showy pink flowers and the species’ heat tolerance.

Planting & stewardship

How to help Desert willow thrive

1
Confirm the plant’s mature spread and underground conflicts before digging.
2
Place the root flare at finished grade and keep mulch away from the trunk.
3
Establish a wide, deep root zone instead of irrigating only at the trunk.
4
Observe seasonal growth, heat stress, and wildlife use before making major pruning changes.
