Native plants are the plants that were found in the local area before European colonization. Over many thousands of years, such plants have adapted to local climate and conditions and co-evolved with local wildlife, microbes, fungi, and other plants to form a complex network of relationships and the entire ecosystem's foundation.
It is best to seek out native plants that have been sourced from as close as possible to their planted location.
