How to grow healthy broad-leaved evergreen trees

Start with a hardiness check

  • The most dependable indicator of a tree's hardiness is the lowest temperature it can endure in winter.
  • To determine whether a specific tree can be expected to survive in the area where you live, check the zone designation for that tree in the Hardiness column.
  • Then, look at a Hardiness Zone Map at Natural Resources Canada.
  • The Zone Map divides the country into nine different climatic zones, based on average minimum winter temperatures, frost-free periods and so on.

  • Good to Zone 7
  • This tree features toothed leaves on sticky, hairy branches. The leaves are a glossy dark green with red stems and grow 8-10 cm (3-4 in) long.
  • White blooms, tinted pink or greenish, hang in 5-cm (2-in) clusters.
  • The tree has strawberry-like fruits, hence the name. They're edible but not very tasty.
  • Both blooms and fruits appear in fall.
  • The reddish inner bark makes an attractive display when the outside cover peels and cracks.
