Anacis verticillata

Threadleaf tickseed is a flowering herbaceous perennial, native to eastern Canada and eastern United States, and a member of the daisy family that grows in dense bushy clumps. It may grow 2 to 3 feet tall with a similar spread. The delicate, dark-green leaves of this poplular garden flower are divided into thread-like segments and the long-blooming flower heads have yellow centers and untoothed petals. It is fairly common in the central and eastern Piedmont of North Carolina, but less so in the mountains, western Piedmont, or Coastal Plain.

This plant thrives with full sun to partial shade in infertile sandy and rocky soils and tolerates drought, low levels of salt, infertile soil, heat, and humidity.  If the soil is too rich or moist, stems become weak and plants tend to flop. The clumps will spread by rhizomes and can be divided every 2-3 years. It will also self-seed. Shearing the plant after blooming will sometimes produce fall flowers.

Propagate by dividing either in the fall or early spring. Seeds may be sown outside in late fall or the following spring without any cold treatment. Seedlings grow rapidly.

This plant provides an airy appearance to the sunny border, naturalized area, native garden, or mass plantings. Its long bloom season provides a profusion of daisy-like yellow flowers. It is an easy-care plant that will give you years of enjoyment.
