Deer Fern is a perennial grown for its blooms, which open in summer and return year after year. It's hardy across USDA zones 5 through 8 and shrugs off deer.

What Deer Fern is
Deer Fern grows as a perennial and reaches around two feet at maturity. It blooms in summer. It's also deer-resistant.
How to grow Deer Fern
Deer Fern grows in USDA zones 5 through 8. Deer Fern does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.5 to 7. It needs a growing season of at least 160 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant deer fern in part sun with at least 4 hours of direct sun.
Match the soil
Deer Fern prefers pH 5.5 to 7 (USDA PLANTS). 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. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut deer fern blooms in the cool of the morning, just as they open, for the longest display.
Where Deer Fern thrives
Deer Fern 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 Deer Fern stands, state by state
Deer Fern 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.

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 Deer Fern
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.

Frequently asked questions
Can I grow Deer Fern in my zone?
Deer Fern 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.
When should you plant Deer Fern?
Time deer fern to your own season rather than the calendar, leaving enough of the season for its 160-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 Deer Fern need?
Deer Fern does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Deer Fern need?
Deer Fern prefers soil pH 5.5 to 7 (USDA PLANTS). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Deer Fern attract pollinators?
Deer Fern isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Deer Fern safe for pets?
Deer Fern is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
