Barrel Cactus is a perennial grown for its orange blooms, which open in late spring and return year after year. It's hardy across USDA zones 5 through 11, shrugs off deer and shrugs off dry spells. Its late spring flowers are a moderate draw for honeybees and native bees.

What Barrel Cactus is
Barrel Cactus grows as a perennial and reaches around five feet at maturity. It blooms orange in late spring. It's also deer-resistant.
How to grow Barrel Cactus
Barrel Cactus grows in USDA zones 5 through 11. Barrel Cactus does best in full sun — at least 6 hours of direct sun a day — and soil from pH 7 to 8.5, on fast-draining ground.

Start the season right
Plant barrel cactus in full sun with at least 6 hours of direct sun.
Match the soil
Barrel Cactus prefers pH 7 to 8.5 (USDA PLANTS). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water while it roots in
Water deeply while barrel cactus establishes, letting the soil dry between soakings; once its roots are in, it rides out dry spells on its own.
Harvest at its peak
Cut barrel cactus blooms in the cool of the morning, just as they open, for the longest display.
Where Barrel Cactus thrives
Barrel Cactus is hardy across USDA zones 5 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 5–11 spans average winter lows from -20°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 29 outright and splits 21 more down the middle — and which side of that line your land sits on changes the answer.

Where Barrel Cactus stands, state by state
Barrel Cactus is rated for zones 5–11 — a cold floor USDA puts at -20 to -10°F. Across the 50 states and DC, 29 sit fully inside that band, the line runs through 21 more, and 1 sits outside it — and inside every split state, the same line runs on at county grain.

How we know this about Barrel Cactus
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 Barrel Cactus in my zone?
Barrel Cactus grows in USDA hardiness zones 5 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 Barrel Cactus?
Time barrel cactus to your own season rather than the calendar. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Barrel Cactus need?
Barrel Cactus 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 Barrel Cactus need?
Barrel Cactus prefers soil pH 7 to 8.5, on fast-draining ground (USDA PLANTS). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Barrel Cactus attract pollinators?
Yes — barrel cactus's flowers are a solid nectar source for honeybees and native bees. (Source: Lady Bird Johnson Wildflower Center.)
