Celtis is a genus of about 60-70 species of deciduous hackberry trees widespread in warm temperate regions.
Celtis species are generally medium-sized trees, reaching 10–25 m (33–82 ft) tall, rarely up to 40 m (130 ft) tall. The leaves are alternate, simple, 3–15 cm (1.2–5.9 in) long, ovate-acuminate, and evenly serrated margins.
The fruit is a small drupe 6–10 mm (0.24–0.39 in) in diameter, edible in many species, with a dryish but sweet, sugary consistency, reminiscent of a date.

It has a slender trunk that grows to a height of 60 feet in the middle states, but can be much taller the further south it grows. It is not particular where it grows, it prefers moist soil, but will grow on gravelly or rocky hillsides. But it is very particular about sunlight, and must live in full sun in order to survive.
The beauty of the tree is truly in its bark. It is a cork like bark, light brown or silvery gray, smooth for the most part, but often with rough, wart like protuberances. The wood is light yellow, heavy, soft, coarse grained and not strong. The leaves are about 2 to 4 inches long, and at full growth are bright green, rough above, and paler green beneath. In autumn the leaves turn
