For bright seasonal colour and accents, containers and borders, butterflies, hummers, and cut flower bouquets, perennials just can't be beat, and they come back every year to repeat the show!

Perennials 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.
