Crossvine is a climbing vine, a long-term addition to the landscape. It's hardy across USDA zones 5 through 9 and shrugs off deer. Its summer flowers are a real draw for hummingbirds and native bees. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Crossvine is
Crossvine grows as a perennial and reaches around 50 feet at maturity. It blooms orange in summer. It's also deer-resistant.
How to grow Crossvine
Crossvine grows in USDA zones 5 through 9. Crossvine does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.5 to 7.5, on well-drained ground. It needs around 2,000 growing degree days to mature, which is why climate matters as much as soil.

Start the season right
Plant crossvine in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Crossvine prefers pH 5.5 to 7.5 (Growable Ground Plant Database). 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 its peak
Cut crossvine blooms in the cool of the morning, just as they open, for the longest display.
Where Crossvine thrives
Crossvine is hardy across USDA zones 5 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 5–9 spans average winter lows from -20°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 25 outright and splits 25 more down the middle — and which side of that line your land sits on changes the answer.

Where Crossvine stands, state by state
Crossvine is rated for zones 5–9 — a cold floor USDA puts at -20 to -10°F. Across the 50 states and DC, 25 sit fully inside that band, the line runs through 25 more, and 1 sits outside it — and inside every split state, the same line runs on at county grain.

How we know this about Crossvine
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 Crossvine in my zone?
Crossvine grows in USDA hardiness zones 5 through 9 (Rated hardy to zone 5a by NC State Extension Gardener Plant Toolbox, checked Oct 2026. Ceiling: not verified.). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Crossvine?
Most growers plant crossvine 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 Crossvine need?
Crossvine 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 Crossvine need?
Crossvine prefers soil pH 5.5 to 7.5, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Crossvine attract pollinators?
Yes — crossvine's flowers are a strong nectar and pollen source for hummingbirds and native bees. (Source: Lady Bird Johnson Wildflower Center.)
