Desert Willow is a tree, a long-term addition to the landscape. It's hardy across USDA zones 7 through 9 and shrugs off dry spells. Its mid spring flowers are a real draw for native bees and hummingbirds.

What Desert Willow is
Desert Willow grows as a perennial and reaches around 25 feet at maturity. It blooms purple in mid spring.
How to grow Desert Willow
Desert Willow grows in USDA zones 7 through 9. Desert Willow does best in full sun — at least 6 hours of direct sun a day — and soil from pH 6.6 to 8.5, on fast-draining ground.

Plant it right
Set desert willow in full sun with fast-draining soil.
Match the soil
Desert Willow prefers pH 6.6 to 8.5 (Growable Ground Plant Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water while it roots in
Water deeply while desert willow establishes, letting the soil dry between soakings; once its roots are in, it rides out dry spells on its own.
Shape it while it is young
Prune desert willow only to remove dead, damaged or crossing branches while it is young; it is grown for its form, not a harvest, so little more is needed once it settles in.
Where Desert Willow thrives
Desert Willow is hardy across USDA zones 7 through 9. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 7–9 spans average winter lows from 0°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 6 outright and splits 35 more down the middle — and which side of that line your land sits on changes the answer.

Where Desert Willow stands, state by state
Desert Willow is rated for zones 7–9 — a cold floor USDA puts at 0 to 10°F. Across the 50 states and DC, 6 sit fully inside that band, the line runs through 35 more, and 10 sit outside it — and inside every split state, the same line runs on at county grain.

How we know this about Desert Willow
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Desert Willow in my zone?
Desert Willow grows in USDA hardiness zones 7 through 9. Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Desert Willow?
Set desert willow out in early spring or fall while it's dormant, so the roots establish before the heat of summer. Your local last-frost date — which a Growable Ground report pulls for your exact address — sets the precise window.
How much sun does Desert Willow need?
Desert Willow needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Desert Willow need?
Desert Willow prefers soil pH 6.6 to 8.5, on fast-draining ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Desert Willow attract pollinators?
Yes — desert willow's flowers are a strong nectar and pollen source for native bees and hummingbirds. (Source: Lady Bird Johnson Wildflower Center.)
