Acer rubrum ‘Franksred’ RED SUNSET
This cultivar of the red maple (Acer rubrum) certainly lives up to its common name – the fire engine red leaves put on a fabulous show in the fall. This highly adaptable tree can be used in a variety of situations from standing water to parking lot medians. Fall foliage color is dependent on species, temperature, sunlight, and soil moisture.
Leaves are green because they have chlorophyll in them. As chlorophyll production slows in the fall, the underlying yellow (xanthophyll) and orange (carotenoid) pigments are unmasked. The brilliant red colors maples turn in the fall are produced by anthocyanins, thought to act as a sort of “sunscreen” for leaves though their purpose is not fully understood. When the weather conditions come together the fall show can add an additional element of interest to the garden, especially in a time of year when many blooming perennials and shrubs are slowing down for winter.
