Pereunial aud Bcennial Flower Seeds 
Many hardy perennials and biennials (plants that require two years to produce bloom, after which they set seed and die) are 
easily grown from seed. An important thing to remember is that seed should be started as early as possible in order to develop 
good-sized plants which will winter over easily. Seedlings of most perennials can be carried over winter with the protection ofa 
light mulch. Most bienntals, however, require covering or wintering in a coldframe, especially in exposed areas. Raising your 
own plants from seed is an easy and inexpensive way to develop a perennial border.
