Flowers We Love in Our Zone 3 Garden

Alberta has a dry climate with low humidity, which can make it challenging to grow certain types of flowers. When starting your flower garden in Alberta it's important to choose flowers that are tolerant of colder temperatures and shorter growing seasons.


A Zone 3 garden refers to a garden that is located in a region with a USDA hardiness zone rating of 3. This means the garden is located in an area with an average minimum winter temperature between -34 to -40 degrees Celsius.


That's cold!


Alberta has a hardiness zone rating of 3 which means we need to grow hardy flowers.


Some of the best flowers for gardens in Zone 3 include Black-eyed Susans, Coneflowers, Daylilies, Lupines, Marigolds, Sunflowers and Zinnias. These flowers are hardy enough to withstand the colder temperatures and shorter growing seasons of north of the 49th parallel. You'll find all of these varieties grown at Horse Hill Flowers.

Sunflowers in Zone 3 Gardens

Sunflowers can be grown in zone 3, but it's important to choose a variety that is hardy enough to withstand the cold temperatures. Some recommended varieties for zone 3 include 'Russian Giant', 'Moulin Rouge', and 'Autumn Beauty'. It's also a good idea to start the seeds indoors and transplant them outside once the danger of frost has passed.


Sunflowers are beautiful, bright yellow flowers that are native to North and Central America. They are known for their large, circular heads that follow the movement of the sun throughout the day. Sunflowers are often used for decorative purposes and can also be harvested for their oil-rich seeds.


Our favourite sunflower to grow is the Panache Sunflower!

Zinnias in Zone 3 Gardens

Zinnias come in a variety of colours and are often grown for their vibrant blooms! They're a workhorse flower in our garden and one of our favourite additions to cut flower bouquets.


Zinnias are able to thrive in zone 3 due to their ability to tolerate cooler temperatures and adapt to a variety of soil types. Additionally, proper care and maintenance, such as regular watering and fertilization, can also help zinnias thrive in this zone.



With love always,
