Sea Grape is a perennial grown for its fruit. It's hardy across USDA zones 10 through 11, stands up to deer and handles dry spells once it's established. Its indeterminate flowers are a moderate draw for honeybees and native bees, even though the fruit is the prize.

What Sea Grape is
Sea Grape grows as a perennial. It blooms white in indeterminate. It's also deer-resistant.
How to grow Sea Grape
Sea Grape grows in USDA zones 10 through 11. Sea Grape does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.8 to 8, on well-drained ground.

Start the season right
Plant sea grape in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Sea Grape prefers pH 5.8 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 while it roots in
Water deeply while sea grape establishes, letting the soil dry between soakings; once its roots are in, it rides out dry spells on its own.
Harvest at maturity
Pick when the fruit is full-colored and parts easily from the stem. Local Cooperative Extension guides publish timing tables.
Where Sea Grape thrives
Sea Grape is hardy across USDA zones 10 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 10–11 spans average winter lows from 30°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 8 down the middle — and which side of that line your land sits on changes the answer.

Where Sea Grape stands, state by state
Sea Grape is rated for zones 10–11 — a cold floor USDA puts at 30 to 40°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 8 more, and 43 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.

Good to know
Sea Grape offers moderate value to bees and other pollinators.
Before you harvest sea grape, know your soil
Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant sea grape for food. Our free screen reads 8 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.
Your land is one point inside Sea Grape'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 exact soil pH, drainage, sun exposure, and frost dates shape whether sea grape actually takes — we score it against the real conditions at your address.

How we know this about Sea Grape
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 Sea Grape in my zone?
Sea Grape grows in USDA hardiness zones 10 through 11 (Rated hardy to zone 10 by UF/IFAS EDIS ENH334/ST175, checked Oct 2026. Ceiling: UF/IFAS EDIS ENH334/ST175 (read 2026-10-05).). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Sea Grape?
Most growers plant sea grape 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 Sea Grape need?
Sea Grape 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 Sea Grape need?
Sea Grape prefers soil pH 5.8 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Sea Grape attract pollinators?
Yes — sea grape's flowers are a solid nectar source for honeybees and native bees.
