Growing broad-leaved evergreen trees requires a keen gardening eye and some knowledge of what to expect. Here’s some stats and tips on growing four of these trees, and how to help them stay healthy.
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.

- Height: 3-7.5 m (10-25 ft)

- 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.
