Lungwort is grown for its blooms, which open in summer. It's hardy across USDA zones 4 through 8 and shrugs off deer. Its summer flowers are a moderate draw for honeybees and native bees.

Start the season right
Plant lungwort in full sun.
Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match lungwort'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 lungwort blooms in the cool of the morning, just as they open, for the longest display.
Where Lungwort thrives
Lungwort 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 Lungwort stands, state by state
Lungwort 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 Lungwort
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.
