The Butchart Gardens, Victoria, British Columbia
You'd never believe this wonderland of floral displays on a Vancouver Island inlet started as an industrial wasteland. In 1904, Jennie Butchart began landscaping a played-out quarry left by her husband's cement business. Today, more than 1 million bedding plants keep the 55-acre gardens in glorious bloom from March into October. Illumination makes it even lovelier on summer evenings; 866/652-4422 or butchartgardens.com.
