Coreopsis

A perennial plant or simply perennial (Latin per, "through", annus, "year") is a plant that lives for more than two years.

When used by gardeners or horticulturalists, perennial applies specifically to winter hardy herbaceous plants.

Perennials, especially small flowering plants, grow and bloom over the spring and summer and then die back every autumn and winter, then return in the spring from their root-stock rather than seeding themselves as an annual plant does. These are known as herbaceous perennials.
