How we know this about Bells Of Ireland
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 Bells Of Ireland in my zone?
Bells Of Ireland is grown as an annual, so a hardiness zone does not decide it — its growing season follows your last and first frost dates. Soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Bells Of Ireland?
Bells Of Ireland 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 Bells Of Ireland need?
Bells Of Ireland needs full sun — a spot that catches at least 6 hours of direct summer sun a day. We haven't confirmed this against a published source yet. 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 Bells Of Ireland need?
Bells Of Ireland prefers soil pH 6 to 7.5, on well-drained ground. We haven't confirmed this against a published source yet. Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Bells Of Ireland attract pollinators?
Yes — bells of ireland's flowers are a solid nectar source for honeybees and native bees. We haven't confirmed this against a published source yet.
