Cypress Vine is a perennial grown for its red blooms, which open in summer and return year after year. It's hardy across USDA zones 11 through 12, shrugs off deer and grows just as well in a container as in the ground. Its summer flowers are a real draw for hummingbirds and butterflies.

What Cypress Vine is
Cypress Vine grows as a perennial and reaches around ten feet at maturity. It blooms red in summer. It's also deer-resistant and well suited to containers.

How to grow Cypress Vine
Cypress Vine grows in USDA zones 11 through 12. Cypress Vine 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 2,500 growing degree days to mature, which is why climate matters as much as soil.

Start the season right
Plant cypress vine in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Cypress Vine prefers pH 5.5 to 7.5. 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.
Water steadily
Keep the root zone evenly moist through establishment. We haven't confirmed this against a published source yet. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at its peak
Cut cypress vine blooms in the cool of the morning, just as they open, for the longest display.
Where Cypress Vine thrives
Cypress Vine is hardy across USDA zones 11 through 12. 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 11–12 spans average winter lows from 40°F to 60°F (USDA PHZM 2023). Across the 50 states and DC, that band covers none outright but splits 3 down the middle — and which side of that line your land sits on changes the answer.

Where Cypress Vine stands, state by state
Cypress Vine is rated for zones 11–12 — a cold floor USDA puts at 40 to 50°F. Across the 50 states and DC, 0 sit fully inside that band, the line runs through 3 more, and 48 sit outside it — and inside every split state, the same line runs on at county grain.

3 states
- California · zones 4b-11a
- Florida · zones 8b-12a
- Hawaii · zones 8b-13a
Cypress Vine’s band covers part of each of these states — which side of the line your county sits on changes the answer, and each state page draws it.
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
One caution for pet owners — cypress vine 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.)
Cypress Vine is a standout pollinator plant — high value to bees and other pollinators. We haven't confirmed this against a published source yet.

How we know this about Cypress Vine
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 Cypress Vine in my zone?
Cypress Vine grows in USDA hardiness zones 11 through 12 (Rated hardy to zone 11a 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 Cypress Vine?
Most growers plant cypress vine 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 Cypress Vine need?
Cypress Vine 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 Cypress Vine need?
Cypress Vine prefers soil pH 5.5 to 7.5, 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 Cypress Vine attract pollinators?
Yes — cypress vine's flowers are a strong nectar and pollen source for hummingbirds and butterflies. We haven't confirmed this against a published source yet.
Is Cypress Vine safe for pets?
Cypress Vine 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.)
