Alvars are Ontario’s wild rock gardens. The word is Swedish but the most of the world’s alvars are found in Ontario. They are home to some unique species of plants, birds, insects and other invertebrates. The plants in alvars are adapted to extreme conditions of drought and heat, qualities that make them valuable components of ecologically-responsible gardening, xeriscaping, and roof gardening.
