Except for a temporary cover matrix utilizing some combination of seed oats, timothy, and annual rye, non-native plants should not be used in habitat restoration projects. Limited exceptions are often made if a client requests instant color. In those cases, short-lived, non-native, noninvasive
annual wildflowers are added to a seed mix. These non-native forbs and grasses will gradually be out-competed as the native species become established.
In a landscape setting, the judicious use of non-native plants is acceptable. Special care must be given to assure that exotic, invasive species are never used in a landscape project. Stunning effects can often be created by mixing native with non-native plants. Just remember that non-native plants will often require more care and maintenance than their native counterparts. With foresight and planning, a landscape design can take advantage of the benefits that native plants offer and still provide for ample display and enjoyment of non-native annuals and perennials.
