Do Coreopsis Come Back Every Year. Perennials come back every year growing from roots that survive through the winter. As with many native plants coreopsis care is limited to occasional watering during extreme drought along with the deadheading and trimming described above.
Can I grow coreopsis in containers. Perennials have a shorter bloom period than annuals the tradeoff being that they come back every year. Some types of tickseed are only annual strains while others are perennials.

I have Ive tried to kill in years past and they keep coming back. Expect a perennial to spend the first growing season establishing itself as a plant. I grow other cultivars of the Coreopsis and a couple of other species of Lobelia and they werent the first things to come back for me when our spring started. Unlike plants that are strictly annual meaning that they live for one year and then die the roots of perennial flowers survive through winter allowing the plant to come back up in the spring.
