About this reference

Why native plants matter in Canadian ecosystems

Native plants evolved alongside local insects, birds, and soil organisms over thousands of years. They require less supplemental water once established, support specialist pollinators that cannot use introduced species, and contribute to the regional seed banks that allow ecosystems to recover from disturbance.

Across Canada, grassland, boreal, and temperate forest zones each harbour distinct plant communities. Identifying and preserving these communities — even at the scale of a single garden — contributes to the broader ecological network that sustains migratory species and soil health.

This reference draws on publicly available botanical records, provincial flora guides, and herbarium data. Species accounts focus on identification features, native range, and ecological roles rather than commercial availability.

Field Identification

Leaf shape, flower structure, bark texture, and seasonal markers for accurate species recognition in the field.

Planting Guidance

Soil, light, and moisture requirements based on each species' natural habitat zone across Canadian provinces.

Ecological Context

Notes on pollinator relationships, seed dispersal mechanisms, and the species' role in its native plant community.

Conservation Status

Provincial and federal status designations from COSEWIC and provincial conservation programs where applicable.
