Small deciduous trees can be planted to screen a south-facing patio or wall during the summer, but let the sun shine into the windows throughout the cold weather, while a clump of evergreens can form a quiet backdrop for a colourful flowerbed, then – touched up with snow – show off all winter long. If you're lucky enough to have a yard beneath a canopy of statuesque maples or other giants, an understory of short, shade-tolerant specimens can hover between the garden beds and the tallest trees, softening the space. One tree can be a focal point; two can frame a gate or pathway.
What to consider
• Decide if you prefer an upright, horizontal or weeping form. Do you want something that splashes out with showy flowers in the spring or colourful fruit in the fall? Or a tree, such as crab apple, that does both? What matters most: a variety with bright leaves all season or one with attention-grabbing autumn colour?
• Plant some native species for their easy-care attributes, as well as their eco-friendliness.
• Choose a tree that can spread to its full size without outgrowing its site, and suits the scale of its surroundings.
• Match the sun and soil requirements of the tree to the planting spot.
• Avoid planting fruiting varieties where they will overhang paved pathways, and steer clear of any with toxic fruit if you have young children.
• Remember that fruiting plants bring birds into your yard from late summer through winter.
