Native shrubs that flower for pollinators, fruit for birds, and give the garden its year-round backbone and structure. Every species here is genuinely native to Maine and the wider flora of the Northeast and hardy through zones 3–6 — proven performers for Maine's cool, short summers climate across Acadian forest & coastal lowlands, not a generic list. Local standouts include Winterberry and Smooth Hydrangea. Shrubs are the bones of a garden — they hold their shape through winter, screen what you would rather not see, and pack flowers, berries, and fall color into a single long-lived plant. Give them room to reach full size rather than shearing them into boxes, plant in fall for the best root establishment, and choose species suited to your light and moisture so they thrive on near-zero care.
