This cool-climate garden renovation has been designed as a richly layered, seasonal perennial landscape that brings colour, movement, and texture throughout the year. The scheme retains and celebrates the three key existing trees—the ornamental cherry (Prunus sp.), pink flowering dogwood (Cornus florida var. rubra), and Cotinus (Cotinus coggygria ‘Grace’)—which anchor the garden and connect the new planting to the home’s heritage character.
