The swamp tickseed is a native perennial in the daisy or sunflower family (Asteraceae). It is a native, but rare plant in North Carolina to NE Florida. It grows in swamp forests, wet loamy pine savannas, and swamp edges in its native habitat. The common name, Tickseed, is based on the seed appearance which has two short spines at one oval end and looks like a ‘tick’.
Swamp tickseed can grow in various soils, but prefers moist well-drained soils and full sun. It can also tolerate flooding. The plant will grow up to 30” and should be planted 2’ – 3’ apart. It spreads slowly by self-seeding and rhizomes.
The swamp Ttckseed is a valuable late-blooming yellow daisy-like wildflower for pollinators. The native plant is prone to powdery mildew which can result in defoliation by September. However, the ‘Summer Sunshine’ cultivar has disease-resistant foliage and is widely available commercially. It is easy to grow the showy ‘Summer Sunshine’ cultivar which can bloom up to six weeks.
The swamp tickseed can be grown in containers and borders. Plant it in a pollinator, native, or cutting garden where the soil is moist. It can also be planted along a water source or rain garden. Insects,
