A pollinator garden does not need a long plant list. A handful of native flowering species, chosen to suit the region and spaced so insects can work them efficiently, usually does more than a crowded bed of unfamiliar ornamentals. This note collects species that are widely documented as native across southern and central Canada, along with the kinds of bees and butterflies that tend to visit them.
Why “native” is the useful filter
Native plants and local insects share a long history. Many of Canada's wild bees are solitary and short-lived, and some collect pollen from only a small group of related plants. Choosing species that already occur in your province or ecozone raises the chance that the nectar and pollen on offer match what local pollinators can actually use.
Provincial and conservation sources publish regional native-plant guidance worth consulting before buying. The Canadian Wildlife Federation and the Pollinator Partnership both maintain region-aware material that can point you to species suited to your area.
Plant in groups, not singletons. Several plants of one species placed together let a foraging bee collect from many flowers in one trip, which is more efficient for the insect than a scattered planting.
A starter palette
Milkweeds (Asclepias species)
Milkweeds are the host plants for monarch caterpillars, and their flowers are also visited by a range of bees and other insects. Common milkweed (Asclepias syriaca) and swamp milkweed (Asclepias incarnata) are widely grown; butterfly weed (Asclepias tuberosa) is a shorter, orange-flowered option for drier, sunny spots. Monarchs are a species of conservation concern, so milkweed earns a place in many Canadian pollinator gardens.
Wild bergamot (Monarda fistulosa)
A mint-family perennial with lavender flower heads, wild bergamot blooms in mid to late summer and is a favourite of bumble bees and other long-tongued bees. It tolerates a range of soils and tends to spread gently once established.
Black-eyed Susan (Rudbeckia hirta)
This familiar yellow daisy is easy to establish and flowers through mid and late summer. Its open, accessible flowers suit shorter-tongued bees and small butterflies, and the seed heads are left standing into winter for birds.
New England aster (Symphyotrichum novae-angliae)
Asters carry the garden into autumn, when many other flowers have finished. New England aster's purple blooms are an important late-season source for bumble bees building up before winter and for monarchs fuelling their southward migration.
Goldenrods (Solidago species)
Goldenrods are frequently misblamed for hay fever, which is usually caused by wind-pollinated ragweed flowering at the same time. Goldenrod pollen is heavy and insect-carried, and the plants are heavily visited by bees and other insects in late summer and fall.
Matching plants to your conditions
Before choosing, look honestly at the site: sun hours, soil moisture and drainage, and how much room the plants can spread into. Many native perennials prefer full sun; some, such as swamp milkweed, take moister ground. Reading the conditions a plant evolved in is more reliable than choosing on flower colour alone.
- Full sun, dry: butterfly weed, black-eyed Susan.
- Full sun, average to moist: wild bergamot, New England aster.
- Moist ground: swamp milkweed.
Where possible, buy plants or seed from nurseries that label provincial provenance and confirm plants were not treated with systemic insecticides. Avoid digging plants from the wild.
Where to go next
Once you have a palette, the next question is timing: arranging species so that something is in flower from spring through fall. That sequencing is covered in the bloom timing note. The structural side of a garden — nesting sites, water and shelter — is covered in the habitat features note.
