2020 – Whorled Tickseed

Whorled Tickseed is an herbaceous perennial native to Eastern North America. It grows 2.5 to 3 feet tall and spreads 1.5 to 2 feet in zones 3 to 9. Yellow daisy-like flowers appear June through September and are attractive to butterflies and other pollinators. Once Whorled Tickseed is established, it can survive tough conditions including full sun, drought, shallow-rocky soil, and deer pressure.

The foliage has an airy, thread-like appearance. Foliage may be cut back in the summer if sprawling occurs or to encourage fall rebloom. Indicative to its name, tickseed is named after the seeds’ resemblance to ticks.

Whorled Tickseed looks nice in naturalized or cottage gardens where it has room move. It self-seeds and spreads by rhizomes. It pairs nicely with other wildflowers, especially those with purple blooms. Its cheery-yellow color looks nice as a cut flower. Popular cultivars include ‘Moonbeam’, which has a paler yellow flower, and ‘Zagreb’ which is more compact and has slightly darker disks.
