Devils Tree is grown for its foliage and the structure it brings to a planting. It's hardy across USDA zones 10 through 12. Its spring flowers are a moderate draw for moths and butterflies. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Devils Tree is
Devils Tree grows as a perennial. It blooms in spring.
How to grow Devils Tree
Devils Tree grows in USDA zones 10 through 12. Devils Tree does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.5 to 7.5, on well-drained ground. It needs a growing season of at least 300 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant devils tree in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Devils Tree prefers pH 4.5 to 7.5 (USDA PLANTS Database). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Keep it in good form
Prune devils tree to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
Good to know
One caution for pet owners — devils tree is toxic to dogs and cats (moderate severity). Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)

Where Devils Tree thrives
Devils Tree is hardy across USDA zones 10 through 12. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Devils Tree in my zone?
Devils Tree grows in USDA hardiness zones 10 through 12 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Devils Tree?
Most growers plant devils tree after the last spring frost, once the soil has warmed, leaving enough of the season for its 300-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Devils Tree need?
Devils Tree 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 Devils Tree need?
Devils Tree prefers soil pH 4.5 to 7.5, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Devils Tree attract pollinators?
Yes — devils tree's flowers are a solid nectar source for moths and butterflies (Xerces Society, Pollinator Partnership).
Is Devils Tree safe for pets?
Devils Tree is toxic to pets (dogs,cats) with moderate severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency.
