Perennials are plants that live from season to season in contrast to annuals that live one year or season and then die. Technically trees and shrubs are perennials but usually the term usually refers to herbaceous plants.
Evergreen perennials usually bloom during one season and keep their green leaves all year.
Primrose (Primula polyanthus) comes in a wide range of colors and prefers part shade. It starts blooming in February and continues until June when the hot weather comes.
