Using native plants in your landscape supports and enhances local environments and habitat for wildlife, birds and pollinators. Native plants are a great benefit to any landscape: Native plants require minimal or no water once they are established, they do not require additional fertilizers or pesticides, natives increase the biodiversity of an area, and native plants can be planted in place of a lawn, so mowing is not necessary.

Native plants are great for streamside planting, providing food and shelter for wildlife and pollinators, and they are usually easy to grow. Native plants are adapted to the local climate and soils, and can tolerate cool, wet winters and warm dry summers. They do not require added fertilizers, and once established after a year or two of summer watering, they rarely need supplemental water.

Staff from the Marion SWCD can help you identify native plants that may already exist in your landscape. You can start here by viewing some of the most common native plants in the Willamette Valley. If you have a question about a particular plant that is growing on your property, bring in a sample of the plant (with flowers if possible) to the District office or if you are curious about many plants, contact us to schedule a site visit to your property.

To assist district residents identify native on their property or make native selections at area nurseries Marion SWCD has complied a list that can be found in the Willamette Valley.
