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.
Life cycle and bloom period: We haven't confirmed this against a published source yet.
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.

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. We haven't confirmed this against a published source yet.
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.
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.
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.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 9–11 spans average winter lows from 20°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 17 down the middle — and which side of that line your land sits on changes the answer.

Where Kurrajong stands, state by state
Kurrajong is rated for zones 9–11 — a cold floor USDA puts at 20 to 30°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 17 more, and 34 sit outside it — and inside every split state, the same line runs on at county grain.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

How we know this about Kurrajong
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 Kurrajong in my zone?
Kurrajong grows in USDA hardiness zones 9 through 11. 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. 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. We haven't confirmed this against a published source yet. 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 mapped 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. We haven't confirmed this against a published source yet.
