Bloodroot is a perennial grown for its white blooms, which open in summer and return year after year. It's hardy across USDA zones 3 through 8 and shrugs off deer. Its summer flowers are a moderate draw for native bees.

What Bloodroot is
Bloodroot grows as a perennial and reaches around 10 inches at maturity. It blooms white in summer. It's also deer-resistant.
How to grow Bloodroot
Bloodroot grows in USDA zones 3 through 8. Bloodroot does best in shade — at least 2 hours of direct sun a day — and soil from pH 5.5 to 7.2, on well-drained ground.

Start the season right
Plant bloodroot in shade with at least 2 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
Bloodroot prefers pH 5.5 to 7.2 (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 bloodroot blooms in the cool of the morning, just as they open, for the longest display.
Where Bloodroot thrives
Bloodroot is hardy across USDA zones 3 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 3–8 spans average winter lows from -40°F to 20°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 34 outright and splits 17 more down the middle — and which side of that line your land sits on changes the answer.

Where Bloodroot stands, state by state
Bloodroot is rated for zones 3–8 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 34 sit fully inside that band, the line runs through 17 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Bloodroot’s band covers part of each of these states — which side of the line your county sits on changes the answer, and each state page draws it.
State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

Good to know
One caution for pet owners — bloodroot is toxic to dogs and cats (moderate 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 Bloodroot
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 Bloodroot in my zone?
Bloodroot grows in USDA hardiness zones 3 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 Bloodroot?
Bloodroot 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 Bloodroot need?
Bloodroot is shade-tolerant — it gets by on as little as 2 hours of direct sun, so it earns a place most vegetables can't use. A north-facing strip or the ground under a leafy canopy is right where it belongs. A Growable Ground report shows which corners of your land stay shaded through the day, turning those dim spots into planting spots.
What soil does Bloodroot need?
Bloodroot prefers soil pH 5.5 to 7.2, on well-drained ground (Growable Ground Plant Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Bloodroot attract pollinators?
Yes — bloodroot's flowers are a solid nectar source for native bees. (Source: Lady Bird Johnson Wildflower Center.)
Is Bloodroot safe for pets?
Bloodroot is toxic to pets (dogs,cats) with moderate severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
