What Black Eyed Susan is
Black Eyed Susan reaches around a foot at maturity. It blooms orange in summer. It's also deer-resistant.
How to grow Black Eyed Susan
Black Eyed Susan grows in USDA zones 3 through 7. Black Eyed Susan does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.5 to 8, on well-drained ground. It needs around 1,000 growing degree days to mature, which is why climate matters as much as soil.

Start the season right
Plant black eyed susan in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Black Eyed Susan prefers pH 5.5 to 8 (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
Cut black eyed susan blooms in the cool of the morning, just as they open, for the longest display.
Where Black Eyed Susan thrives
Black Eyed Susan is hardy across USDA zones 3 through 7. 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 3–7 spans average winter lows from -40°F to 10°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 23 outright and splits 25 more down the middle — and which side of that line your land sits on changes the answer.

Where Black Eyed Susan stands, state by state
Black Eyed Susan is rated for zones 3–7 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 23 sit fully inside that band, the line runs through 25 more, and 3 sit outside it — and inside every split state, the same line runs on at county grain.

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.

How we know this about Black Eyed Susan
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 Black Eyed Susan in my zone?
Black Eyed Susan grows in USDA hardiness zones 3 through 7 (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 Black Eyed Susan?
Most growers plant black eyed susan after the last spring frost, once the soil has warmed. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Black Eyed Susan need?
Black Eyed Susan 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 Black Eyed Susan need?
Black Eyed Susan prefers soil pH 5.5 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Black Eyed Susan attract pollinators?
Yes — black eyed susan's flowers are a strong nectar and pollen source for honeybees, native bees, and butterflies. (Source: Xerces Society.)
Is Black Eyed Susan safe for pets?
Black Eyed Susan is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
