Native and Invasive Plants
The strongest support for the use of native plants may be that it addresses ecological concerns of maintaining biological diversity of plants and the animals that rely on them for food and shelter. The plants and animals of our region evolved together and depend on one another for survival.
Native plants attract and feed native birds and butterflies, as well as other beneficial insects. They provide habitat for birds and other small animals, which are the predators of many garden pests, as well as the food source for majestic predators like hawks and eagles.
Native species are utilitarian, for in addition to being attractive and sometimes tougher than introduced species, they provide food and shelter for local wildlife.
