Lavender is a perennial medicinal herb, long valued for its traditional uses. It's hardy across USDA zones 5 through 8, stands up to deer and handles dry spells once it's established. Its summer flowers are a real draw for honeybees, native bees, and butterflies.

What Lavender is
Lavender grows as a perennial and reaches around two feet at maturity. It blooms purple in summer. It's also deer-resistant.
How to grow Lavender
Lavender grows in USDA zones 5 through 8 and is ready to harvest about 120 days after planting. Lavender does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.8 to 8.3, on well-drained to fast-draining ground. It needs around 2,500 growing degree days to mature and a growing season of at least 180 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant lavender 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
Lavender prefers pH 5.8 to 8.3 (FAO ECOCROP). 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
Harvest the part you grow lavender for — flower, leaf, or root — at its seasonal peak.
Where Lavender thrives
Lavender is hardy across USDA zones 5 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 5–8 spans average winter lows from -20°F to 20°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 19 outright and splits 31 more down the middle — and which side of that line your land sits on changes the answer.

Where Lavender stands, state by state
Lavender is rated for zones 5–8 — a cold floor USDA puts at -20 to -10°F. Across the 50 states and DC, 19 sit fully inside that band, the line runs through 31 more, and 1 sits outside it — and inside every split state, the same line runs on at county grain.

In rotation planning, lavender counts as a Other — beds recover best when other crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)
Good to know
One caution for pet owners — lavender 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.)

Before you harvest lavender, know your soil
Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant lavender for food. Our free screen reads 9 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.

How we know this about Lavender
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 Lavender in my zone?
Lavender grows in USDA hardiness zones 5 through 8 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Lavender take to grow?
Lavender is ready to harvest about 120 days after planting (UMD-Herb; RHS). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Lavender?
Lavender 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 Lavender need?
Lavender 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 Lavender need?
Lavender prefers soil pH 5.8 to 8.3, on well-drained to fast-draining ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Lavender attract pollinators?
Yes — lavender's flowers are a strong nectar and pollen source for honeybees, native bees, and butterflies. (Source: Xerces Society.)
Is Lavender safe for pets?
Lavender 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.)
