By choosing a few plants for your landscape that are among the last to display excellent fall color each year, you can extend the fall color season by two to three weeks.
Shrubs that provide very nice late fall color and interest include the hydrangeas,
Emerald Carousel Barberry, Golden Carousel Barberry, Grace Smokebush, Clethra, Grow-Low Sumac and the rusty orange color of the Tamarisk.
Trees that consistently provide excellent late season fall color include Red Oak, Northern Pin Oak, Red Sunset Maple, Autumn Fantasy Maple, Green Mountain Sugar Maple, Dakota Pinnacle Birch, American Larch , Hydrangea trees and the Grace Smoketree.
The picture here is just two days ago of our Limelight Hydrangea tree in our yard. It started blossoming in late August and is still providing an incredible visual feast!
