Weigela is a perennial grown for its blooms, which open in spring and return year after year. It's hardy across USDA zones 4 through 8. Its spring flowers are a moderate draw for honeybees, native bees, and hummingbirds.

What Weigela is
Weigela grows as a perennial and reaches around ten feet at maturity. It blooms in spring.
How to grow Weigela
Weigela grows in USDA zones 4 through 8. Weigela does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.5 to 7.5, on well-drained ground. It needs a growing season of at least 110 frost-free days and about 500 hours of winter chill, which is why climate matters as much as soil.

Start the season right
Plant weigela in full sun with at least 6 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
Weigela prefers pH 5.5 to 7.5 (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 weigela blooms in the cool of the morning, just as they open, for the longest display.
Where Weigela thrives
Weigela is hardy across USDA zones 4 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 4–8 spans average winter lows from -30°F to 20°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 25 outright and splits 26 more down the middle — and which side of that line your land sits on changes the answer.

Where Weigela stands, state by state
Weigela is rated for zones 4–8 — a cold floor USDA puts at -30 to -20°F. Across the 50 states and DC, 25 sit fully inside that band, the line runs through 26 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

How we know this about Weigela
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 Weigela in my zone?
Weigela grows in USDA hardiness zones 4 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 Weigela?
Weigela 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 Weigela need?
Weigela needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Weigela need?
Weigela prefers soil pH 5.5 to 7.5, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Weigela attract pollinators?
Yes — weigela's flowers are a solid nectar source for honeybees, native bees, and hummingbirds. (Source: Pollinator Partnership.)
Is Weigela safe for pets?
Weigela is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
