This deciduous tree features gracefully lobed leaves that emerge vibrant red in spring, intensify through summer, and transform into an attractive scarlet hue in autumn, adding multi-season interest to landscapes. 'Red Emperor' is prized for its heat tolerance and ability to maintain its color better than similar varieties.
