Marsh Marigold is a perennial grown for its yellow blooms, which open in mid spring and return year after year. It's hardy across USDA zones 3 through 7, shrugs off deer and grows just as well in a container as in the ground. Its mid spring flowers are a moderate draw for native bees.

What Marsh Marigold is
Marsh Marigold grows as a perennial and reaches around a foot and a half at maturity. It blooms yellow in mid spring. It's also deer-resistant and well suited to containers.
How to grow Marsh Marigold
Marsh Marigold grows in USDA zones 3 through 7. Marsh Marigold does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.8 to 7.3, on consistently moist 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 marsh marigold in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Marsh Marigold prefers pH 4.8 to 7.3 (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. Match watering to the plant's drainage preference and your local rainfall.
Harvest at its peak
Cut marsh marigold blooms in the cool of the morning, just as they open, for the longest display.
Good to know
One caution for pet owners — marsh marigold 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.)

Where Marsh Marigold thrives
Marsh Marigold 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.

Frequently Asked Questions
Can I grow Marsh Marigold in my zone?
Marsh Marigold 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 Marsh Marigold?
Most growers plant marsh marigold 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 Marsh Marigold need?
Marsh Marigold 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 Marsh Marigold need?
Marsh Marigold prefers soil pH 4.8 to 7.3, on consistently moist ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Marsh Marigold attract pollinators?
Yes — marsh marigold's flowers are a solid nectar source for native bees (Xerces Society, Pollinator Partnership).
Is Marsh Marigold safe for pets?
Marsh Marigold 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.
