Scarlet Sentinel maple (Acer rubrum 'Scarlet Sentinel') is a deciduous tree that is commonly used as an ornamental tree in landscapes. It is a cultivar of the red maple, and can grow up to 40 to 50 feet (12 to 15 meters) tall and 15 to 20 feet (4.5 to 6 meters) wide.
The tree has an upright, columnar habit with a narrow, symmetrical canopy, and produces small, red flowers in the spring that are followed by paired, winged fruit in the fall. Its foliage is a deep, green color throughout the growing season, turning a bright scarlet-red color in the fall. The Scarlet Sentinel maple has a smooth, gray bark when young, which eventually develops some furrows and fissures as the tree matures.
Scarlet Sentinel maple is known for its striking foliage color, its adaptability to a range of soil types and environmental conditions, and its resistance to pests and diseases. It is also tolerant of urban pollution
