Heather is a perennial grown for its blooms, which open in summer and return year after year. It's hardy across USDA zones 4 through 6 and shrugs off deer. Its summer flowers are a moderate draw for honeybees and native bees.

What Heather is
Heather grows as a perennial and reaches around two feet at maturity. It blooms in summer. It's also deer-resistant.
Mature height and bloom period: We haven't confirmed this against a published source yet.
How to grow Heather
Heather grows in USDA zones 4 through 6. Heather does best in part sun — at least 4 hours of direct sun a day — and soil from pH 4.5 to 7, on well-drained ground.

Start the season right
Plant heather in part sun with at least 4 hours of direct sun. We haven't confirmed this against a published source yet.
Match the soil
Heather prefers pH 4.5 to 7 (FAO ECOCROP). 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. We haven't confirmed this against a published source yet. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at its peak
Cut heather blooms in the cool of the morning, just as they open, for the longest display.
Where Heather thrives
Heather is hardy across USDA zones 4 through 6. 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 4–6 spans average winter lows from -30°F to 0°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 4 outright and splits 38 more down the middle — and which side of that line your land sits on changes the answer.

Where Heather stands, state by state
Heather is rated for zones 4–6 — a cold floor USDA puts at -30 to -20°F. Across the 50 states and DC, 4 sit fully inside that band, the line runs through 38 more, and 9 sit outside it — and inside every split state, the same line runs on at county grain.

Good to know
Heather offers moderate value to bees and other pollinators. We haven't confirmed this against a published source yet.
Your land is one point inside Heather's range
This page resolves to the species. Your state page draws the county line, and a report reads the parcel — the soil pH, drainage, sun, and frost dates on your exact ground, which no species average can see.
See if Heather will thrive on your land
Zone averages are a start. Your soil pH, drainage, sun exposure, and frost dates shape whether heather actually takes. We score it against the mapped and modelled conditions at your address.

How we know this about Heather
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 Heather in my zone?
Heather grows in USDA hardiness zones 4 through 6 (NC State Extension Gardener Plant Toolbox). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Heather?
Time heather to your own season rather than the calendar. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Heather need?
Heather does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. We haven't confirmed this against a published source yet. 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 Heather need?
Heather prefers soil pH 4.5 to 7, on well-drained ground (FAO ECOCROP). Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Heather attract pollinators?
Yes — heather's flowers are a solid nectar source for honeybees and native bees. We haven't confirmed this against a published source yet.
