Anthurium 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 modest draw for native bees.

What Anthurium is
Anthurium grows as a perennial and reaches around a foot and a half at maturity. It blooms red in summer. It's also deer-resistant and well suited to containers.
How to grow Anthurium
Anthurium grows in USDA zones 11 through 12. Anthurium does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.5 to 6.5, on well-drained ground.

Start the season right
Plant anthurium in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Anthurium prefers pH 5.5 to 6.5 (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 anthurium blooms in the cool of the morning, just as they open, for the longest display.
Where Anthurium thrives
Anthurium 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 Anthurium stands, state by state
Anthurium 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.
The line runs through
3 states
- California · zones 4b-11a
- Florida · zones 8b-12a
- Hawaii · zones 8b-13a
Anthurium’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 — anthurium is toxic to dogs and cats (moderate 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 Anthurium
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 Anthurium in my zone?
Anthurium grows in USDA hardiness zones 11 through 12 (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 Anthurium?
Most growers plant anthurium 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 Anthurium need?
Anthurium does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Anthurium need?
Anthurium prefers soil pH 5.5 to 6.5, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Anthurium attract pollinators?
Yes — anthurium's flowers are a modest nectar source for native bees.
Is Anthurium safe for pets?
Anthurium is toxic to pets (dogs,cats) with moderate severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
