Kurrajong is grown for its foliage and the structure it brings to a planting. It's hardy across USDA zones 9 through 11. Its spring flowers are a moderate draw for honeybees and native bees. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Kurrajong is
Kurrajong grows as a perennial. It blooms in spring.
How to grow Kurrajong
Kurrajong grows in USDA zones 9 through 11. Kurrajong does best in full sun — at least 6 hours of direct sun a day — and soil from pH 6.5 to 8.5, on well-drained ground. It needs a growing season of at least 90 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant kurrajong in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Kurrajong prefers pH 6.5 to 8.5 (FAO ECOCROP). 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 kurrajong 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
Good news for pet owners — kurrajong isn't known to be toxic to dogs or cats. (Source: ASPCA.)
Kurrajong offers moderate value to bees and other pollinators.
Where Kurrajong thrives
Kurrajong is hardy across USDA zones 9 through 11. 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 Kurrajong in my zone?
Kurrajong grows in USDA hardiness zones 9 through 11 (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 Kurrajong?
Most growers plant kurrajong after the last spring frost, once the soil has warmed, leaving enough of the season for its 90-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 Kurrajong need?
Kurrajong 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 Kurrajong need?
Kurrajong prefers soil pH 6.5 to 8.5, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Kurrajong attract pollinators?
Yes — kurrajong's flowers are a solid nectar source for honeybees and native bees.
Is Kurrajong safe for pets?
Kurrajong is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
