Trumpet Vine is a perennial grown for its red blooms, which open in summer and return year after year. It's hardy across USDA zones 4 through 9, shrugs off deer and shrugs off dry spells. Its summer flowers are a real draw for hummingbirds and native bees.

What Trumpet Vine is
Trumpet Vine grows as a perennial and reaches around two feet at maturity. It blooms red in summer. It's also deer-resistant.
How to grow Trumpet Vine
Trumpet Vine grows in USDA zones 4 through 9. Trumpet Vine does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 8, on well-drained ground. It needs around 2,000 growing degree days to mature and a growing season of at least 120 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant trumpet 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
Trumpet Vine prefers pH 5 to 8 (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 trumpet vine blooms in the cool of the morning, just as they open, for the longest display.
Where Trumpet Vine thrives
Trumpet Vine is hardy across USDA zones 4 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 4–9 spans average winter lows from -30°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 33 outright and splits 18 more down the middle — and which side of that line your land sits on changes the answer.

Where Trumpet Vine stands, state by state
Trumpet Vine is rated for zones 4–9 — a cold floor USDA puts at -30 to -20°F. Across the 50 states and DC, 33 sit fully inside that band, the line runs through 18 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Good to know
One caution for pet owners — trumpet 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: ASPCA.)

How we know this about Trumpet 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 Trumpet Vine in my zone?
Trumpet Vine grows in USDA hardiness zones 4 through 9 (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 Trumpet Vine?
Most growers plant trumpet vine after the last spring frost, once the soil has warmed, leaving enough of the season for its 120-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 Trumpet Vine need?
Trumpet 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 Trumpet Vine need?
Trumpet Vine prefers soil pH 5 to 8, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Trumpet Vine attract pollinators?
Yes — trumpet vine's flowers are a strong nectar and pollen source for hummingbirds and native bees. (Source: Lady Bird Johnson Wildflower Center.)
Is Trumpet Vine safe for pets?
Trumpet Vine is toxic to pets (dogs,cats) with mild severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
