Autumn Sage is a perennial grown for its blooms, which open in summer and return year after year. It's hardy across USDA zones 7 through 9, shrugs off deer and shrugs off dry spells. Its summer flowers are a real draw for honeybees, native bees, butterflies, and hummingbirds.

What Autumn Sage is
Autumn Sage grows as a perennial and reaches around three feet at maturity. It blooms in summer. It's also deer-resistant.
How to grow Autumn Sage
Autumn Sage grows in USDA zones 7 through 9. Autumn Sage does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.2 to 8.3, on well-drained ground. It needs a growing season of at least 120 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant autumn sage in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Autumn Sage prefers pH 4.2 to 8.3 (USDA PLANTS 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 autumn sage blooms in the cool of the morning, just as they open, for the longest display.

Where Autumn Sage thrives
Autumn Sage is hardy across USDA zones 7 through 9. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Autumn Sage in my zone?
Autumn Sage grows in USDA hardiness zones 7 through 9 (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 Autumn Sage?
Most growers plant autumn sage after the last spring frost, once the soil has warmed, leaving enough of the season for its 120-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Autumn Sage need?
Autumn Sage 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 Autumn Sage need?
Autumn Sage prefers soil pH 4.2 to 8.3, on well-drained ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Autumn Sage attract pollinators?
Yes — autumn sage's flowers are a strong nectar and pollen source for honeybees, native bees, butterflies, and hummingbirds (Xerces Society, Pollinator Partnership).
Is Autumn Sage safe for pets?
Autumn Sage is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
