Why plant natives

Native plants evolved with the local insects, birds, and soils, so once established they need little water, no fertilizer, and no coddling, while providing the nectar, pollen, seeds, and host foliage that non-native ornamentals cannot. A native bed is lower-maintenance and higher-value for wildlife than a conventional one.

Starting a native garden in Ontario

Start by matching plant to place: note how much sun each spot gets and whether the soil runs dry, moist, or wet, then choose species whose needs match; the filters above sort by exactly these. In Ontario (roughly Canadian zones 3a–7a), fall and early spring are the prime planting windows. Buy nursery-propagated, local-genotype plants rather than wild-collected stock, plant in groups of three or more so pollinators can find them, and mulch lightly the first year while roots establish.

Keep it blooming

The species here bloom from March through October. Pick at least one plant for each part of that window (spring, summer, and fall) so something is always in flower and pollinators always have forage.

Frequently asked

How many native plants are native to Ontario?
This guide features 184 native plants documented as native to Ontario, including wildflowers, ferns, and shrubs. Many hundreds more native species also grow wild in the province.
What hardiness zone is Ontario in?
Ontario spans roughly Canadian hardiness zones 3a–7a. Check your exact zone before buying, since the province covers more than one.
When do Ontario wildflowers bloom?
Across these species, bloom runs from March through October. Planting a mix of spring, summer, and fall bloomers keeps color and pollinator forage going all season.
What are the best native plants for pollinators in Ontario?
167 of these Ontario natives have documented bee, butterfly, or hummingbird visitors. Use the "For pollinators" filter above to rank them by pollinator value.
Where can I buy native plants in Ontario?
Look for a nursery that sells nursery-propagated (not wild-collected) local-genotype plants. Your state native plant society and regional native-plant sales are the best starting points; see Resources below.
