The local asparagus you find in Edmonton was pioneered by Doug and Elna Edgar of Edgar Farms. Despite the prevailing wisdom that the spring vegetable was not a viable crop for our province, that did not stop the Edgars from deciding to grow it in their farm back in 1986.
“It is a blessing having it accessible all throughout the year, through imports, but it doesn’t beat the fresh thing,” says Elna. In Alberta, asparagus season goes for six to eight weeks, between May and the end of June. And that’s the only time we can savour “fresh, beautiful, sweet and tender asparagus.”
Sweet Grass
Ordinary seventeenth-century English people called it “sparrow grass,” a possibly deliberate mispronunciation of asparagus, which was a newly-introduced delicacy of the day. Surprisingly, there are still quite a few people who have never tried asparagus.
So, for the curious, Elna describes the raw vegetable as tasting similar to baby peas. It shares a similar vegetal flavour profile to other grassy tasting vegetables — think brussel sprouts, broccoli and spinach.
The sweetness of the crop is another detail to note. Based west of Innisfail in Red Deer County, Edgar Farms benefits from its proximity to the mountains. Elna explains that “growing them closer to the mountains affects them too because the cool nighttime temperatures increase the sugar content.”
Art of Harvesting
“People think it is a greenhouse crop — that is a big misconception,” says Elna. “It is an outdoor plant, the roots are in the ground.”
Asparagus is a perennial vegetable, which means it requires a few years for its crowns (root) to fully establish. But once matured, it can produce a spring harvest of edible spears for more than 15 years.
The spears are also fast growing during warm weather. Asparagus can grow seven to 10 inches in a single day. During peak season, they are harvested daily (or on an extra hot day, twice in a day).
