Some coreopsis are perennial—living more than one year, others are annual—living for only one year. … Some may be perennial in warmer climates, but not live over winter in colder climates. Use annual coreopsis in front of taller summer perennials such as garden phlox, bee balm, or coneflowers.

Do coreopsis grow back every year?

Perennial coreopsis are tough and reliable plants for creating summer colour. They are herbaceous perennials, dying back in winter and regrowing the following spring to give colour year after year.

Will my coreopsis come back?

All you have to do once the earth thaws and all danger of frost has passed is cut the dead stems down to just two to three inches above the ground, and new flowers will grow. If you must have a neat, clean look in your garden throughout the winter, you can cut your coreopsis down to four to six inches above the ground.
