Chelone is a perennial grown for its pink blooms, which open in summer and return year after year. It's hardy across USDA zones 3 through 8, shrugs off deer and grows just as well in a container as in the ground. Its summer flowers are a real draw for native bees, butterflies, and hummingbirds.

What Chelone is
Chelone grows as a perennial and reaches around three feet at maturity. It blooms pink in summer. It's also deer-resistant and well suited to containers.
How to grow Chelone
Chelone grows in USDA zones 3 through 8. Chelone does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5 to 7, on consistently moist ground.

Start the season right
Plant chelone in part sun with at least 4 hours of direct sun. It grows in the cool halves of the year, so sow it in spring or late summer rather than waiting for midsummer heat.
Match the soil
Chelone prefers pH 5 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. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut chelone blooms in the cool of the morning, just as they open, for the longest display.
Where Chelone thrives
Chelone is hardy across USDA zones 3 through 8. 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 3–8 spans average winter lows from -40°F to 20°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 34 outright and splits 17 more down the middle — and which side of that line your land sits on changes the answer.

Where Chelone stands, state by state
Chelone is rated for zones 3–8 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 34 sit fully inside that band, the line runs through 17 more, and 0 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 Chelone
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 Chelone in my zone?
Chelone grows in USDA hardiness zones 3 through 8 (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 Chelone?
Chelone is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Chelone need?
Chelone 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 Chelone need?
Chelone prefers soil pH 5 to 7, on consistently moist ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Chelone attract pollinators?
Yes — chelone's flowers are a strong nectar and pollen source for native bees, butterflies, and hummingbirds. (Source: Lady Bird Johnson Wildflower Center.)
Is Chelone safe for pets?
Chelone is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
