Ask your nursery for perennials. Annuals live for one growing season, and then need to be re-planted next spring. Biennials are planted one year, and bloom the next. Perennials live 3-20+ years, blooming every year. Some perennials--such as mums--need to be dug up, divided, and replanted every 3-4 years to stay healthy and maintain bloom, while others--such as gaura--can stay in the same spot for decades, blooming away.

Exactly so Tug.
