Best visited during the late spring, summer and early autumn, the Toronto Botanical Garden is located entirely outdoors, which means blooms are dependent on the season. Divided into 17 different gardens, which range from native Carolinian Forest habitat to Renaissance-inspired formal gardens, if offers plenty to explore. Landscaping aficionados will be delighted by Dutch garden designer Piet Oudolf’s Entry Garden Walk, planted in the New Wave Planting style. Oudolf allowed flowers and shrubs to self-seed for 3 years, creating sculptural "sophisticated meadows" that aren’t just beautiful when blossoming, but striking well into late autumn. For budding botanists, the Teaching Garden includes demonstrations that teach youngsters how to sow seeds and harvest veggies. Younger ones might prefer meandering through the Alphabet Garden, where plants A through Z are planted.
