Tuberose is a perennial grown for its root. It's hardy across USDA zones 7 through 11 and handles dry spells once it's established. Its indeterminate flowers are a moderate draw for moths and butterflies, even though the root is the prize.

What Tuberose is
Tuberose grows as a perennial. It blooms yellow in indeterminate.
How to grow Tuberose
Tuberose grows in USDA zones 7 through 11. Tuberose does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.5 to 8, on well-drained ground. It needs a growing season of at least 150 frost-free days, which is why climate matters as much as soil.

Sow directly
Sow tuberose seed straight into the bed — root crops germinate fast and resent transplanting. Give them full sun.
Match the soil
Tuberose prefers pH 5.5 to 8 (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.
Harvest at maturity
Pull while roots are young and tender — sweeter than oversized ones. Local Cooperative Extension guides publish timing tables.
Where Tuberose thrives
Tuberose is hardy across USDA zones 7 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 7–11 spans average winter lows from 0°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 7 outright and splits 34 more down the middle — and which side of that line your land sits on changes the answer.

Where Tuberose stands, state by state
Tuberose is rated for zones 7–11 — a cold floor USDA puts at 0 to 10°F. Across the 50 states and DC, 7 sit fully inside that band, the line runs through 34 more, and 10 sit outside it — and inside every split state, the same line runs on at county grain.

How we know this about Tuberose
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 Tuberose in my zone?
Tuberose grows in USDA hardiness zones 7 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 Tuberose?
Most growers plant tuberose after the last spring frost, once the soil has warmed, leaving enough of the season for its 150-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 Tuberose need?
Tuberose 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 Tuberose need?
Tuberose prefers soil pH 5.5 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Tuberose attract pollinators?
Yes — tuberose's flowers are a solid nectar source for moths and butterflies.
Is Tuberose safe for pets?
Tuberose is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
