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

Start the season right
Plant bugbane in full sun.
Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match bugbane's needs before planting.
Water steadily
Keep the root zone evenly moist through establishment. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut bugbane blooms in the cool of the morning, just as they open, for the longest display.
Where Bugbane thrives
Bugbane 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 Bugbane stands, state by state
Bugbane 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.

Bugbane’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.

One caution for pet owners — bugbane 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 Bugbane
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 Bugbane in my zone?
Bugbane 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 Bugbane?
Time bugbane 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.
What soil does Bugbane need?
Specific pH data for bugbane is pending. A soil test from your local Extension lab confirms what your site needs.
Does Bugbane attract pollinators?
Yes — bugbane's flowers are a solid nectar source for native bees. (Source: Lady Bird Johnson Wildflower Center.)
Is Bugbane safe for pets?
Bugbane 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.)
