What Heather is
Heather grows as a perennial and reaches around two feet at maturity. It blooms in summer. It's also deer-resistant.
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.
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. 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.
Good to know

Heather offers moderate value to bees and other pollinators.
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.

Frequently Asked Questions
Can I grow Heather in my zone?
Heather grows in USDA hardiness zones 4 through 6 (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 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. 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 actual 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.
Is Heather safe for pets?
Heather is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
