Mosaiculture should be distinguished from topiary, which features mostly shrubs pruned to create different shapes. Mosaiculture is a horticultural art that involves creating and mounting colourful two- and three-dimensional designs, sculptures and reliefs made primarily from plants with colourful foliage that consists generally of annuals, and occasionally perennials.

Mosaïcultures Internationales, a triennial competition, is an exhibition of horticultural art and a chance for the representatives from parks, gardens and green spaces around the world to exchange ideas. All works presented must represent something of the participant’s culture while responding to a predefined theme and complying with the principles of sustainable development. A few of the exhibits from the 2013 competition at the Montreal Botanical Garden are shown here.
