The Columnar Crimson Sentry Maple is an ideal tree for small gardens, confined spaces, and urban privacy screens. It naturally grows into a tight, narrow column reaching about 7.5 - 9 m (25 - 30 ft) tall and 3 - 4.5 m (10 - 15 ft) wide. The tree is celebrated for its deep burgundy and purple foliage that holds its colour all summer before transitioning to a brilliant red-bronze in the fall.
