From the latin per, meaning “through,” and annual, meaning “year,” perennial plants are ones that live for more than two years (as distinguished from annuals and biennials). These plants usually grow and flower in the spring and summer and die back or go dormant in the fall and winter. Many perennials are grown as annuals in more temperate climates (such as the tomato, which is technically a perennial in tropical regions). It’s always a good idea to plant perennials together in your garden since they won’t be replanted the next year.
