Description

Coreopsis verticillata is a dense clump-forming plant that grows up to 3' tall. The common name "threadleaf coreopsis" is a reference to its finely divided, plume-like foliage. It produces clusters of abundant yellow, daisy-like flowers. Unlike Coreopsis auriculata, the petals are not toothed.

Cultivation

Coreopsis verticillata is a low maintenance species, tolerant of poor soils, and dry conditions. It will be at its best in full sun. An excellent choice for cottage and rock gardens alike, where it will provide several months of constant bloom. Deadheading will increase the bloom period. If plants begin to deteriorate during the summer heat, they can be cut back which will encourage a secondary fall bloom season. It can be an aggressive spreader, both by rhizomes and by seed. Mature clumps should be divided to ensure their vigor. Bloom times are from June to September. Zones 5-8

Propagation

Whorled tickseed is very easy to propagate either from seed without any pretreatment, or by division in spring.

Additional Notes

Coreopsis verticillata is very easy to grow and makes a good entry level plant. Its tolerance of dry conditions and poor soil, make it an ideal species for container gardening. Adding to its long list of assets, is its resistance to deer.
