1000 Scarlet Toothcup Seeds – Native Wetland Wildflower & Pond Plant

Scarlet Toothcup (Ammannia coccinea) is a native wetland wildflower prized for its small but vivid scarlet-red flowers that bloom along upright stems in summer and early fall. This moisture-loving annual is naturally found in wet meadows, marshes, and along pond and stream edges, making it an excellent choice for rain gardens, bog plantings, and shallow-water margins.

Its compact size and bright blooms add color and texture to water features and native plant gardens, while the nectar-rich flowers attract bees, butterflies, and other pollinators. Scarlet Toothcup works well as a naturalizing plant in consistently wet soils and can be grown in containers or bog baskets for flexible placement around ponds.

Planting & Care

Sow Scarlet Toothcup seeds on the surface of moist, fine-textured soil and press them gently in place without covering deeply, as light aids germination. Keep the soil consistently wet and maintain high humidity around the seed tray or planting area. Seeds can be started indoors or sown directly in boggy ground, rain gardens, or shallow pond margins after the danger of frost has passed.

Once established, plants need little care beyond steady moisture. Water regularly to prevent the soil from drying out, especially during hot weather. Thin or space seedlings to about 6 to 12 inches apart so plants have room to branch and bloom. Remove spent flowers if you want to limit self-seeding, or allow seed heads to mature to encourage natural spread in wet garden areas.
