Native Plant Requirements

What is a Native Plant?

RPBCWD definition of native plants: 

Plants that are native to the region between central Minnesota and central Iowa. Native plants must be in their natural, wild form. Cultivars (cultivated varieties) of native plants are not permitted.

For a list of recommended plants, check out our list of Favorite Native Plants for Suburban Yards.

Visit the Minnesota Wildflowers website, an online field guide to flora of Minnesota, to help determine if a plant is native or not. There are multiple companies in the Twin Cities Metro that specialize in native plants and offer pre-selected combinations of native plants to meet your needs. Check out the resources section at the bottom of this page!

Native Plant Requirements for Cost Share Projects

Some Stewardship Grant projects (native planting, habitat restoration, shoreline restoration, and waterbody buffer) require the use of native plants. These projects must meet the below requirements. We have experts who can help with plant selection!

• Wild form: Native plants must be in their wild form. No cultivars (cultivated varieties) are allowed. Learn tips for selecting native plants in our Grow Wild handout.
• Approved source: Native plants must be purchased from a reliable native plant grower/vendor. See the "Resources" section at the bottom of the Stewardship Grant webpage for a list of potential vendors.
• Appropriate selection: Plant selection must be appropriate for site conditions. In other words, evaluate your site’s sun exposure and soil conditions and pick plants that will do well there. Avoid purchasing plants that have been container-grown for more than a couple of years – these plants are usually less healthy. Smaller plants are also more cost-effective!
• Blooms in each season: Plant selection must include at least 9 different species with 3 species that bloom in spring, 3 that bloom in summer, and 3 that bloom in fall. All flowering plants including trees, shrubs, and grasses count! You can use this list of Favorite Native Plants for Suburban Yards conveniently organized by bloom time.
• Keystone species: Plant selection must include at least one (1) keystone species, which is a plant that supports the wildlife food web (birds, insects, etc.).  Your keystone species can be the same as a plant counted toward the "blooms in each season" requirement. See the resources section on the Stewardship Grant webpage for a list of keystone species.
• Ecologically friendly maintenance: You must use ecologically friendly maintenance techniques. This means limiting chemicals and leaving plant material in place. See “Ecologically Friendly Maintenance” below for details.​​​​

What Your Native Plant List Should Include

Projects that require native plants (native garden, restoration, and buffer projects) need to provide detailed native plant information. At minimum, the native plant list you submit with your grant application should include the following:

• Native plant source/supplier/vendor - We want to make sure the plant source you're using is reputable.
• Scientific plant name - This is the Latin name including genus and species. For example, Asclepias tuberosa is the scientific name for Butterfly Milkweed. However, some people may call it by another common name such as Butterfly Weed or Orange Milkweed, which is why we want the scientific name.
• Quantity proposed for each species - Are you proposing to plant one or six of an individual species? We realize availability of your proposed list may vary, but don't worry -- we'll allow substitutions and quantity adjustments if you ask us.
• Season of bloom - So the habitat value of your project is maximized, we require at least three different blooming species for spring, summer, and fall. Native plant nursery websites, catalogs, or plant labels will include bloom time. You can also look up plants on Minnesota Wildflowers.

Ecologically Friendly Maintenance

Native plants provide the most benefit when they are given a chance to thrive within a natural, healthy ecosystem.

• Do not use fungicides or insecticides. These kill "good" and "bad" fungi and insects.
• Limit herbicide use to invasive weed control and carefully follow label directions.
• Plan to pull or otherwise control weeds at least three times during the growing season. This reduces competition with native plants.
• Limit fertilizer use to those without harmful salts. Natural fertilizers such as top-dressing with compost or compost tea are preferred. Native plants usually do not need ANY fertilizer. Alternative (bee) lawns: Clover and other legumes fix nitrogen in soil so fertilizer isn't needed.
• Limit watering to the plant establishment phase (usually the first couple of years) or during extended extreme drought.
• Select appropriate weather conditions for proper planting and seeding.
• Provide soft landings (native plants, leaf litter, and plant debris) under trees. Soft landings support overwintering and pupating insects, which serve an important role in nature including serving as food sources for songbirds.
• Practice "messy" gardening. Dead standing plants and fallen leaves provide winter and early spring shelter for beneficial insects, birds, and soil microbes. Leave flower stems no shorter than 18 inches. Even better, don't cut off spent flowers as they provide food for birds year-round.
