Not sure what to plant in spring? Use this Southern Ontario guide to choose perennials, shrubs, natives, and pollinator plants
Once you’ve got a rough plan for where things go, the next question is the one everyone asks: what should you actually plant this spring? In Southern Ontario, the best results come from mixing structure plants (shrubs), reliable perennials, seasonal colour, and native/pollinator plants that thrive once established.
Plant Types That Actually Work Together
Use this as a selection guide:
Perennials
Your “repeat performers.” They come back yearly and build a fuller garden over time.
Good picks: Black-eyed Susan (Rudbeckia hirta), Purple coneflower (Echinacea purpurea), Wild bergamot (Monarda fistulosa), New England aster (Symphyotrichum novae-angliae), Bee balm (native Monarda), Garden phlox (Phlox paniculata), Daylily (Hemerocallis).
Non-perennials (annuals)
Your “instant colour.” Use them to fill gaps and refresh the look each season.
Good picks: Petunia, Calibrachoa (million bells), Marigold, Zinnia, Begonia (shade), Impatiens (shade), Sweet alyssum (edge filler), Nasturtium (easy + trailing), Coleus (colourful foliage in shade/part shade).
Shrubs
Your “structure plants.” They make beds look designed even when nothing is blooming.
Native-leaning + reliable picks: Serviceberry (Amelanchier), Ninebark (Physocarpus opulifolius), Red-osier dogwood (Cornus sericea), Meadow sweet (Spiraea alba), Virginia sweetspire (Itea virginica), Hydrangea paniculata (popular, very hardy), Boxwood (popular for tidy structure—site carefully).
Native plants
Your “low-drama option.” Once established, many handle Southern Ontario conditions well and support local ecosystems.
Great natives to build around: Wild columbine (Aquilegia canadensis), Butterfly milkweed (Asclepias tuberosa), Switchgrass (Panicum virgatum), Little bluestem (Schizachyrium scoparium), Virginia bluebells (Mertensia virginica), Foamflower (Tiarella cordifolia), Canada anemone (Anemone canadensis).
Pollinator plants
Aim for early, mid, and late bloomers so pollinators have food all season—not just one week.
Early: Wild columbine, Virginia bluebells, Golden alexanders (Zizia aurea)
Mid-season: Wild bergamot, Bee balm, Purple coneflower, Butterfly milkweed
Late: New England aster, Smooth aster (Symphyotrichum laeve), Goldenrod (Solidago—pick well-behaved varieties)
