When it comes to planting in our crazy Calgary climate, sometimes we can experience extreme weather changes which can be costly if you’re not picking plants that can survive in our location.

Walk into any garden centre and there is a vast spectrum of perennials to choose from. Some thrive in Calgary better than others.

But how to choose the right one for your garden oasis? We hope this article will help you decide.

Firstly, one important fact you should know is that in 2016 Calgary’s hardiness zone was moved from a 3b to 4a.

This change increased the variety of perennials that you can plant. Most garden centres will carry plants that range in zone from 2 – 7, so be conscious of the choice you make and the zoning of your plant.

The lower the number means the plant will survive in harsher climate, the higher the number the milder the climate.

Secondly, take the time to evaluate your garden to know your sunny and shady areas. Choosing the right plant according to exposure is just as important as zoning.

Full sun generally indicates six or more hours of sunlight per day.

Partial Sun or Partial Shade plants get the morning or evening sun, or a lot of shade in the morning followed by a strong midday sun and then subdued sunlight.

Full Shade plants do best in a protected area with a sprinkling of sunlight throughout the day.

Tall perennials can provide the shade and protection that these types of plants require.

Perennials are plants that die back to their crown every fall but are strong enough to survive the Calgary winter and grow back in the spring.

These lovely plants can make gardening in the spring a lot easier and reduce the amount of work most of us face. There are plenty of perennials that will flourish in the Calgary area.

Our landscape designers have put together a list of their favourites.
