Hardiness Zone Versus Native Status in Alberta
Separate Canadian winter-climate information from Alberta status, natural-region context, occurrence evidence, and garden conditions.
Read guideA useful regional plant search starts with a place, then checks what each map or list can actually show. A state, province, county, ecoregion, occurrence record, hardiness zone, and seed-source label describe different things.

- How to read native-plant range maps and records explains what a result can and cannot establish.
- Which regional plant source should I use? helps match a source to the question you need answered.
- Pennsylvania keystone shrubs by ecoregion uses a regional wildlife-priority list to narrow candidates before checking local range and garden fit.
Use regional evidence as a starting point
A regional list can help you build a candidate set. Before planting, check the identified species, its local status, the conditions at your own site, mature size, and the origin of the material you plan to buy. Climate tolerance does not prove native status, and a recorded occurrence does not guarantee that a plant will fit every garden.
These guides explain how to make those checks. They do not replace a current species record or a site assessment.
