Although most of humanity is fed by the re-sowing of the seeds of annual grain crops, (either naturally or by the manual efforts of man), perennial crops provide numerous benefits. Unlike annual plants (zinnias, marigolds, radish) which complete their life cycle in one growing season and biennials (Sweet William, hollyhocks, onions) which need two growing seasons to mature and go to seed, perennials may go to seed every year. seasons), reproduction, and stage of development to begin and halt the ability to grow or flower. Perennial plants are usually better competitors than annual plants, especially under stable, resource-poor conditions.
