Growing in Zone 3: What Makes It Different?
Often when people picture flower farms, they imagine long summers, early springs, and endless sunshine and good growing weather. As we know, Northern Alberta has other plans.
We’re in Zone 3a, which means our growing season is short, our winters are long, and spring likes to take its sweet time arriving. Just look outside your window, it’s almost May and we still have an abundance of snow on the ground!
All of these variables can make gardening feel a little intimidating at first. However, growing in a colder climate also teaches us to work with our environment instead of against it.
What Does “Zone 3” Actually Mean?
Hardiness Zones help gardeners understand what plants are capable of surviving winter temperatures in a particular region.
Zone 3 is considered a cold climate growing zone, with winter temperatures that can sometimes drop below -35°C. Because of this, gardeners here have to think carefully about:
Frost dates
Cold tolerance
Shorter growing windows
Indoor seed starting
Choosing fast-maturing varieties
You’ll also sometimes see zones divided into “a” and “b” categories. These subgroups reflect slight differences in average winter temperatures.
Zone 3a is colder, with average winter lows around -40°C to -37°C
Zone 3b is slightly milder, with lows around -37°C to -34°C
Unfortunately in Lac La Biche, we’re on the colder side of zone 3. While the difference may seem small, it can actually affect which perennial plants reliably survive winter outdoors and how early gardeners can safely plant in spring.
Not every plant can handle our climate, but many can with the right timing and care.
Our Growing Season Is Short, But Also Busy
One of the most important things to take into account in Zone 3 gardening is timing.
Once spring arrives, everything moves quickly. Trees bud fast, gardens wake up overnight, and growers suddenly go from watching snow melt to trying to keep up with seedlings, hardening off, transplanting, gardening prep and watering all at once.
A lot of our season depends on planning ahead:
Starting seeds indoors
Choosing hardy varieties
Using frost-sensitive plants carefully
Making the most of the warmer months when they arrive
There’s a reason northern gardeners tend to become very good planners.
Cold Hardy Plants Matter
One thing we’ve learned quickly is how important hardy plants are in a northern climate.
Plants adapted to cooler regions often end up being some of the most reliable and rewarding to grow here. Things like Violas, English Daisies, Yarrow, Delphinium, and even Lewisia Cotyledon, a plant naturally found in rocky mountain regions, tend to handle our climate surprisingly well.
That doesn’t mean we avoid less hardy plants annuals entirely. We still grow warm-loving flowers like Marigolds, Cosmos, and Basil, but those plants need a little more patience and protection early in the season.
Pollinators and Biodiversity Still Matter
Short seasons don’t make healthy ecosystems any less important.
In fact, northern gardens can become incredibly valuable spaces for pollinators and wildlife during the warmer months. Every garden filled with flowering plants can help support bees, butterflies, birds, and beneficial insects throughout the season.
Supporting local ecosystems and helping the pollinators is one of our core values. A lot of what we grow is chosen not just because it’s beautiful, but because it contributes something to the ecosystem around it.
Embrace Northern Gardening
Growing flowers in Zone 3 can be unpredictable, occasionally frustrating, and very weather-dependent. But because of that, it also makes the season feel meaningful in a way that’s hard to explain until you experience it yourself.
After six months of snow, the first green shoots feel exciting. The first flowers feel earned. Every small sign of growth becomes something worth celebrating.
You learn patience, flexibility, and how to appreciate the season while it’s here.
And honestly, we wouldn’t trade that for much!
