Violets can make a dense ground-cover, becoming to some a ‘weed’, preferring cool, shady places. Nutritional qualities known for centuries right back to ancient Greece. One hundred grams of fresh spring leaves contains 264mg Vitamin C and 20,000 IU of Vitamin A (put another way; two leaves contain as much Vitamin C as an orange). Supports the liver, gall bladder, digestive and urinary systems. (Julia's Edible Weeds website)
Found escaping out from under a fence on nearby Renfrew Ave. A few flowers out already.
