Botanical description:

Red maple is a deciduous tree that grows 30 to 90 feet (9-28 m) tall and up to 4 feet (1.6 m) in diameter. The bark is smooth and gray but darkens and becomes furrowed in narrow ridges with age. Twigs are stout and shiny red to grayish brown.

The small, fragrant flowers are borne in slender-stalked, drooping, axillary clusters. The fruit is a paired, winged samara, approximately 0.75 inches (1.9 cm) long. Samaras are red, pink, or yellow.

Seasonal development:

Red maple is one of the first trees to flower in early spring. Specific flowering dates are largely dependent on weather conditions, and latitude and elevation. Flowers generally appear several weeks before vegetative buds. Bud break may be affected by soil factors and is typically delayed for 7 to 10 days on copper-, lead-, and zinc-mineralized sites. Fruit matures in spring before leaf development is complete.
