Vine maple is one of the earliest plants to show autumn colors … but there is tremendous variation between individuals. Some are showing colors in mid-summer and others are still showing bright colors in mid to late October.
Washington State isn’t known for a lot of fall colors. The flora isn’t primo and the weather usually doesn’t cooperate. But vine maple provides a lot of color on a reliable basis. Just in a smaller dosage than (for instance) the forests of New England.
