About Swamp Marigold: As the name suggests, Swamp Marigold thrives in the moist ground of marshes, ditches, and woodland areas. Its spreading habit has placed this annual on the invasive list on several states, since it reseeds prolifically in wetland conditions. Its large yellow flowers make it a colorful addition to native wildflower plantings or natural landscaping; the seeds are also a favorite with songbirds. The first specimens of this plant were documented along the Potomac River in 1902. Its Latin name, “bidens,” meaning "with two prongs," refers to the two barbs on the seed.

Swamp Marigold Germination: In late fall, scatter the seed ¼” deep and compact the soil lightly. Keep the soil moist until germination. For spring planting, mix the seed with moist sand and store it in the refrigerator for 60 days before planting. Thin or transplant the seedlings to 18-24” apart. These flowers adapt well to many soil types, but do not do well in sand.

Growing Swamp Marigold Seeds: Though this plant tolerates some drought, it will benefit from regular watering. For the best blooming performance, remove wilted flowers to allow for new ones. In good growing conditions, this plant will reseed and may spread rapidly to the point of being invasive; to prevent reseeding, cut it down after flowering. This plant attracts butterflies, bees, and many beneficial insects.

Harvesting Swamp Marigold: For fresh flowers, cut the stems at ground level and place them in water immediately.

Saving Swamp Marigold Seeds: Since small birds and rodents love to eat these seeds, harvest them promptly to avoid loss. Mature heads will be dark brown; remove them and separate the seed from the husk. Store the seed in a cool, dark place.
