Best Plants for Calgary Gardens: A Local Guide

Gardening in Calgary: Choosing the Right Plants
Selecting the right plants for your Calgary garden can be a challenge. Calgary’s climate, with its short growing season and unpredictable weather, requires hardy varieties. This guide highlights some of the best perennials, annuals, and shrubs that thrive here, ensuring a beautiful and resilient garden.
Understanding the Calgary Climate
Calgary is located in climate zones 3a and 3b, meaning it experiences cold winters and relatively short summers. The average last frost date is typically in late May, and the first frost can occur as early as September. This necessitates selecting plants that can tolerate frost and thrive in cooler temperatures. Resources like the Calgary Horticultural Society offer valuable local advice. Also, consider researching general cold-climate gardening tips for additional guidance.
