Mandevilla is a perennial grown for its pink blooms, which open in summer and return year after year. It's hardy across USDA zones 10 through 11, shrugs off deer and grows just as well in a container as in the ground. Its summer flowers are a moderate draw for butterflies and hummingbirds.

What Mandevilla is
Mandevilla grows as a perennial and reaches around ten feet at maturity. It blooms pink in summer. It's also deer-resistant and well suited to containers.
How to grow Mandevilla
Mandevilla grows in USDA zones 10 through 11. Mandevilla does best in full sun — at least 6 hours of direct sun a day — and soil from pH 6 to 7.5, on well-drained ground. It needs a growing season of at least 180 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant mandevilla in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Mandevilla prefers pH 6 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 mandevilla blooms in the cool of the morning, just as they open, for the longest display.
Good to know
One caution for pet owners — mandevilla 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.)

Where Mandevilla thrives
Mandevilla is hardy across USDA zones 10 through 11. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Mandevilla in my zone?
Mandevilla grows in USDA hardiness zones 10 through 11 (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 Mandevilla?
Most growers plant mandevilla after the last spring frost, once the soil has warmed, leaving enough of the season for its 180-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 Mandevilla need?
Mandevilla 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 Mandevilla need?
Mandevilla prefers soil pH 6 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 Mandevilla attract pollinators?
Yes — mandevilla's flowers are a solid nectar source for butterflies and hummingbirds. (Source: Pollinator Partnership.)
Is Mandevilla safe for pets?
Mandevilla 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.)
