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 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 (USDA PLANTS 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.
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.)
Trumpet Vine is a standout pollinator plant — high value to bees and other pollinators. (Source: Xerces Society, Pollinator Partnership.)
Where Trumpet Vine thrives
Whether trumpet vine thrives on a given site comes down to its soil pH, drainage, sun, and frost dates — the conditions that vary parcel to parcel.

Frequently Asked Questions
Can I grow Trumpet Vine in my zone?
Zone data for trumpet vine is being finalized. A Growable Ground report checks your parcel's full suitability against federal soil, climate, and zone data.
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 (USDA PLANTS 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 (Xerces Society, Pollinator Partnership).
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.
