Native Plant Species

Native plant species have developed naturally and are well adapted to our Canadian environment. They are well-adjusted to the local climate and soil, and don't need as much watering or maintenance as other species. They also improve our community's local ecology and biodiversity, providing homes and food for local wildlife.

Growing native plants on your property in Richmond Hill will help improve the environment, choke our invasive plants and lower your landscaping costs. The following Native Species Guides can help you decide which types of plants to grow in your yard or garden:
