Celtiv laevigata (Sugarberry, Sugar Hackberry)

Tolerant of many soil types, Sugarberry trees are close relatives of Hackberry (C. occidentalis). These trees are quite susceptible to different types of rot and responds poorly to damage. The foliage emerges at slightly different times, a trait rarely seen in deciduous angiosperms.
