Idaho Native Plants
A plant is considered native if it has occurred naturally in a particular region or ecosystem without human introduction. There are many benefits in growing native plants. First, these plants are better adapted to soils, moisture and weather than exotic plants that evolved in other parts of the world. They need less fertilizers, pesticides or use less water. Second, they are unlikely to escape and become invasive, destroying natural habitat. Third, they support wildlife, providing shelter and food for native birds and insects, while exotic plants do not.

They exude an orange aroma when crushed.
