    Quick Tips for Choosing Plants:

    • Planting a variety of native trees, shrubs, perennials and vines increases biodiversity and gives wildlife a source for food, cover and nesting
    • Choose a mixture of deciduous and evergreen trees so birds and other wildlife will always be able to find shelter
    • Plant trees and large shrubs where they will block winter winds from the house and shade it in summer, that will save energy and lower your carbon footprint
    • Try your best to buy plants that were grown locally, your independent garden center will be your best bet
    • Think about ultimate height and width of the plant you choose, make sure it will fit the space you have for it when it's reached maturity
    • Plant nectar plants in groups, to attract butterflies and other beneficial insects more easily
    • Ask for help if you need it. Most garden centers either have a landscape designer on staff or they can give you a reference of a designer that is adept at native plant wildlife gardening. There will be upfront costs but they are small when compared to having to redo a landscape that wasn't what you really wanted

While the “Benefits” section talks about the plants strong suits and how the plant will benefit wildlife. 

    A Special Note About Exposure

    Full sun: Prefers six or more hours of direct sunshine a day
    Partial shade: Thrives in three to six hours of daily sunshine
    Shade: Generally does well with less than three hours of sun per day. Having said that even shade loving plants will struggle in extremely deep shade.
