What is a native plant?native plant is one that originated

and occurs naturally in a region. Non-native plants also may occur naturally,but were introduced from anotherregion. They survive withoutintervention and compete successfullywith native plants. Native and non-native plants often occur side by side innatural stands. Only historical recordscan trace true origin.

Why landscape with native plants?ince native plants are indigenous in

an area, they are ideally suited to growin a similar habitat within the region.Having competed with other plants,native plants have proven themselveswell adapted. Plants used in alandscape environment that is similarto their native habitat will grow with aminimum of maintenance. Whenappropriately placed in the landscape,native plants require less water andfewer pesticide applications. If nativeplants require pampering, the mostlikely reason is an unsuitable location.

Planting native species protects themfrom extinction. As land is developed,some native plants are pushed out oftheir natural habitats. The sensitive useof these plants in the landscapepreserves them for all to appreciate.
