  1. Start the season right

    Plant solomons seal in part sun with at least 4 hours of direct sun.

  2. Match the soil

    Pull a soil test from your local Extension lab to confirm pH and drainage match solomons seal's needs before planting.

  3. Water steadily

    Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.

  4. Harvest at its peak

    Cut solomons seal blooms in the cool of the morning, just as they open, for the longest display.

Where Solomons Seal thrives

Solomons Seal is hardy across USDA zones 3 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 38 spans average winter lows from -40°F to 20°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 34 outright and splits 17 more down the middle — and which side of that line your land sits on changes the answer.

Where Solomons Seal stands, state by state

Solomons Seal is rated for zones 38 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 34 sit fully inside that band, the line runs through 17 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Solomons Seal’s band covers part of each of these states — which side of the line your county sits on changes the answer, and each state page draws it.

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 Solomons Seal

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 Solomons Seal in my zone?

Solomons Seal grows in USDA hardiness zones 3 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 Solomons Seal?

Time solomons seal to your own season rather than the calendar. Your local frost dates set the exact window — a Growable Ground report reads them for your address.

How much sun does Solomons Seal need?

Solomons Seal 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 Solomons Seal need?

Specific pH data for solomons seal is pending. It prefers well-drained ground. A soil test from your local Extension lab confirms what your site needs.

Does Solomons Seal attract pollinators?

Yes — solomons seal's flowers are a solid nectar source for native bees and hummingbirds. (Source: Lady Bird Johnson Wildflower Center.)

Is Solomons Seal safe for pets?
