Mimosa is a tree, a long-term addition to the landscape. It's hardy across USDA zones 6 through 9 and shrugs off deer. Its mid summer flowers are a moderate draw for honeybees, native bees, and butterflies. 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 Mimosa is
Mimosa grows as a perennial and reaches around 35 feet at maturity. It blooms white in mid summer. It's also deer-resistant.
Mature height: We haven't confirmed this against a published source yet.
How to grow Mimosa
Mimosa grows in USDA zones 6 through 9. Mimosa does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.5 to 8.5, on well-drained ground.

Plant it right
Set mimosa in full sun with well-drained soil. We haven't confirmed this against a published source yet.
Match the soil
Mimosa prefers pH 4.5 to 8.5. We haven't confirmed this against a published source yet. 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.
Shape it while it is young
Prune mimosa 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 Mimosa thrives
Mimosa is hardy across USDA zones 6 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 6–9 spans average winter lows from -10°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 14 outright and splits 34 more down the middle — and which side of that line your land sits on changes the answer.

Where Mimosa stands, state by state
Mimosa is rated for zones 6–9 — a cold floor USDA puts at -10 to 0°F. Across the 50 states and DC, 14 sit fully inside that band, the line runs through 34 more, and 3 sit outside it — and inside every split state, the same line runs on at county grain.

Growing guides for mimosa
In rotation planning, mimosa counts as a Legume — beds recover best when legume crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)
Good to know
One caution for pet owners — mimosa is toxic to dogs and cats (mild severity). Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: NC State Extension Gardener Plant Toolbox.)
Mimosa offers moderate value to bees and other pollinators. We haven't confirmed this against a published source yet.
Your land is one point inside Mimosa's range
This page resolves to the species. Your state page draws the county line, and a report reads the parcel — the soil pH, drainage, sun, and frost dates on your exact ground, which no species average can see.

Zone averages are a start. Your soil pH, drainage, sun exposure, and frost dates shape whether mimosa actually takes. We score it against the mapped and modelled conditions at your address.

How we know this about Mimosa
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 Mimosa in my zone?
Mimosa grows in USDA hardiness zones 6 through 9 (Rated hardy to zone 6 by NC State Extension Gardener Plant Toolbox, checked Oct 2026. Ceiling: NC State Extension Gardener Plant Toolbox (read 2026-10-06).). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Mimosa?
Set mimosa 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 Mimosa need?
Mimosa 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 Mimosa need?
Mimosa prefers soil pH 4.5 to 8.5, on well-drained ground. We haven't confirmed this against a published source yet. Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Mimosa attract pollinators?
Yes — mimosa's flowers are a solid nectar source for honeybees, native bees, and butterflies. We haven't confirmed this against a published source yet.
Is Mimosa safe for pets?
Mimosa is toxic to dogs and cats with mild severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: NC State Extension Gardener Plant Toolbox.)
