Lagerstroemia 'Acoma' is a cultivar of the crape myrtle tree, which is a deciduous flowering tree known for its showy blooms, attractive bark, and long blooming period. The term "clear stem" is often used in horticulture to refer to a tree or shrub that has been pruned or trained to have a single, unbranched stem with foliage and branches only at the top, creating a clear and straight trunk.When 'Acoma' is grown with a clear stem, it typically refers to a specific pruning technique where the lower branches and foliage are removed, leaving a tall, bare stem with a rounded or vase-shaped canopy of foliage at the top. This creates a distinctive and formal appearance, often used in formal landscapes, along walkways, or as an accent tree.
