Small Trees Play Big Roles

We’ve all seen it here in the Northwest—trees that loom over houses, towering out of scale for the gardens beneath. Pruning with a chainsaw may be the only option, but the next best strategy is to plant the right-size specimen now. Garden writer Mary-Kate Mackey highlights a fine selection of choice trees that won’t outgrow their welcome. These arboreal show-stoppers with multi-season interest are perfectly suited for today’s gardens and tomorrow’s resale.
