Abstract

A variety of sugar maple, Acer saccharum var. caddo , named ‘WHIT XLV’, is characterized by an upright and oval growth habit at the age of 16 years, but is expected to develop a more rounded crown with age and may reach a height of 30 feet with a 25 foot spread. Leaves emerge medium green and quickly change to very dark glossy green. When adequate spring moisture is present, all leaves on the flush of growth develop full size. However, when spring moisture becomes limiting before all leaves on the twig are produced, the younger leaves will become progressively smaller in size yet the same shape and dark green color. No flowers have been produced on this tree by age 16 years. Fall color develops late in the fall after various species of trees have developed fall color and most of the leaves have fallen.
