Looking for a tree for your yard? Red Maple (Acer rubrum) offers red flower buds and blooms in early spring, green leaves in summer, and brilliant red leaves in fall. Cultivars with good branch structure and reliable fall color include ‘Red Sunset’ and ‘Northwoods’. Be sure to provide acidic soil and be aware that these trees can grow up to 40 – 60 ft. high. Red Maples are hardy in Zones 3 – 9.
