Coral Tree is a tree, a long-term addition to the landscape. It's hardy across USDA zones 10 through 12 and shrugs off deer. Its winter flowers are a real draw for hummingbirds and native bees. A nitrogen-fixer, it draws nitrogen from the air and feeds it back to the soil — turn it under or leave the roots in place, and the next planting inherits a richer bed.

What Coral Tree is
Coral Tree grows as a perennial and reaches around 50 feet at maturity. It blooms red in winter. It's also deer-resistant.
How to grow Coral Tree
Coral Tree grows in USDA zones 10 through 12. Coral 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 180 frost-free days and about 0 hours of winter chill, which is why climate matters as much as soil.

Plant it right
Set coral tree in full sun with well-drained soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.
Match the soil
Coral 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. It fixes its own nitrogen, so skip the high-nitrogen feed and instead dust the seed with a matching rhizobium inoculant at sowing.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Be patient, then harvest
Prune annually while the tree establishes; fruit trees reward patience with years of harvest. Local Extension guides publish per-cultivar bearing-age tables.
Good to know
One caution for pet owners — coral 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 Coral Tree thrives
Coral 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 Coral Tree in my zone?
Coral 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 Coral Tree?
Set coral tree 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 Coral Tree need?
Coral 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 Coral Tree need?
Coral 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 Coral Tree attract pollinators?
Yes — coral tree's flowers are a strong nectar and pollen source for hummingbirds and native bees (Xerces Society, Pollinator Partnership).
Is Coral Tree safe for pets?
Coral 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.
