Spring Blooms: Harbingers of Warmth

Spring in Ontario is a symphony of colour, with flowers emerging from their winter slumber to herald the arrival of warmer days. One of the first to appear is the humble Crocus, its delicate purple or white petals pushing through the thawing earth. The Tulip, Ontario's official flower, follows suit, transforming city parks and gardens into a sea of red, yellow, and white.

The Daffodil, another early bloomer, adds a splash of yellow to woodlands and roadside verges. Meanwhile, the Trillium, Ontario's provincial flower, carpets forests with its three-petaled, white blossoms, often adorned with a splash of red or pink. It's important to note that Trilliums are protected by law, so appreciate them from afar and never pick them.
