Angel Trumpet is a perennial grown for its white blooms, which open in summer and return year after year. It's hardy across USDA zones 8 through 10, shrugs off deer and grows just as well in a container as in the ground. Its summer flowers are a moderate draw for moths and hummingbirds.

What Angel Trumpet is
Angel Trumpet grows as a perennial and reaches around eight feet at maturity. It blooms white in summer. It's also deer-resistant and well suited to containers.
How to grow Angel Trumpet
Angel Trumpet grows in USDA zones 8 through 10. Angel Trumpet does best in full sun — at least 6 hours of direct sun a day — and soil from pH 6 to 7, on well-drained ground. It needs a growing season of at least 150 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant angel trumpet in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Angel Trumpet prefers pH 6 to 7 (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 angel trumpet blooms in the cool of the morning, just as they open, for the longest display.
Where Angel Trumpet thrives
Angel Trumpet is hardy across USDA zones 8 through 10. 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 8–10 spans average winter lows from 10°F to 40°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 1 outright and splits 27 more down the middle — and which side of that line your land sits on changes the answer.

Where Angel Trumpet stands, state by state
Angel Trumpet is rated for zones 8–10 — a cold floor USDA puts at 10 to 20°F. Across the 50 states and DC, 1 sits fully inside that band, the line runs through 27 more, and 23 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.

How we know this about Angel Trumpet
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 Angel Trumpet in my zone?
Angel Trumpet grows in USDA hardiness zones 8 through 10 (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 Angel Trumpet?
Most growers plant angel trumpet after the last spring frost, once the soil has warmed, leaving enough of the season for its 150-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 Angel Trumpet need?
Angel Trumpet 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 Angel Trumpet need?
Angel Trumpet prefers soil pH 6 to 7, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Angel Trumpet attract pollinators?
Yes — angel trumpet's flowers are a solid nectar source for moths and hummingbirds.
Is Angel Trumpet safe for pets?
Angel Trumpet is toxic to pets (dogs,cats) with severe severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
