Winterberry is grown for its foliage and the structure it brings to a planting. It's hardy across USDA zones 4 through 10 and shrugs off deer. Its late spring flowers are a moderate draw for honeybees and native bees.

What Winterberry is
Winterberry grows as a perennial and reaches around eight feet at maturity. It blooms white in late spring. It's also deer-resistant.
How to grow Winterberry
Winterberry grows in USDA zones 4 through 10. Winterberry does best in part sun — at least 4 hours of direct sun a day — and soil from pH 4.5 to 7.5, on well-drained ground. It needs about 400 hours of winter chill, which is why climate matters as much as soil.

Start the season right
Plant winterberry in part sun with at least 4 hours of direct sun.
Match the soil
Winterberry prefers pH 4.5 to 7.5 (USDA PLANTS). 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.
Keep it in good form
Prune winterberry to shape as it grows; the reward is its foliage and structure, not a harvest, so steady upkeep is the whole job.
Where Winterberry thrives
Winterberry is hardy across USDA zones 4 through 10. 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 4–10 spans average winter lows from -30°F to 40°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 38 outright and splits 13 more down the middle — and which side of that line your land sits on changes the answer.

Where Winterberry stands, state by state
Winterberry is rated for zones 4–10 — a cold floor USDA puts at -30 to -20°F. Across the 50 states and DC, 38 sit fully inside that band, the line runs through 13 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Growing guides for winterberry
In rotation planning, winterberry counts as a Other — beds recover best when other crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)
Good to know
One caution for pet owners — winterberry 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.)

How we know this about Winterberry
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 Winterberry in my zone?
Winterberry grows in USDA hardiness zones 4 through 10 (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 Winterberry?
Time winterberry 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 Winterberry need?
Winterberry 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 Winterberry need?
Winterberry prefers soil pH 4.5 to 7.5, on well-drained ground (USDA PLANTS). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Winterberry attract pollinators?
Yes — winterberry's flowers are a solid nectar source for honeybees and native bees. (Source: Lady Bird Johnson Wildflower Center.)
Is Winterberry safe for pets?
Winterberry 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.)
