Bear in mind the potential for your planting beds. Placement should be determined by the size at maturity, thereby creating a balanced effect. Consulting a plant hardiness zone map, found in most garden catalogs will give geographically specific planting schedules. Identifying high ground, low or wet sites, shaded areas and that which receives full sun, gives perspective as to what types of planting you want and where to place it. Also, consider the effects of prevailing winds in determining placement.
Variety is key.
Planting of tall trees, small trees, shrubs and annuals in a layered effect will meet the needs of many species. There are birds that will enjoy roosting in tree tops, yet nest in lower, more dense shrubs. Your goal is to provide food, escape cover, summer nesting, roosting sites and winter shelter. Summer fruiting plants that produce May through August will attract brown thrashes, robins, cardinals, woodpeckers and thrushes. Vines, such as, native grapes, cypress and honeysuckle provide excellent perches, nesting and food.
