Red Maple blooms in late winter or very early spring, before leaf-out. In central North Carolina, they start blooming as early as the end of February, the first tree to bring color to the winter landscape.

The tiny staminate (male) flowers are pale yellowish-red with excerted stamens. This tree is unusually late in blooming, a couple of weeks after the peak in the area.
