Rainy Side Notes
The coral bark maple is a popular tree with beautiful yellow-green leaves, tinged with red in spring. Later in fall, the leaves turn shades of apricot and gold. The bright, coral-red bark is its most outstanding feature during the winter season. Young branches, two years old or less, possess the bright color, while the mature branches fade back into the landscape.

During its youth this maple is a strong grower, quickly making its vase-shaped presence a handsome focal point in the landscape.
T.H. Lowinsky introduced the coral bark maple into Europe where it's called A. 'Senkaki', although Daisy Hill Nurseries in Ireland may have introduced it into Great Britain. Its Japanese name, 'Sangokaku', means "coral tower."
In the Pacific Northwest, it was chosen as a Great Plant Pick.
