Hackberry — Hackberry (Celtis) is a genus of about 60-70 species of deciduous trees widespread in warm temperate regions of the Northern Hemisphere, in southern Europe, southern and eastern Asia, and southern and central North America, and south to central Africa. The genus is present in the fossil record at least since the Miocene of Europe.
They are generally medium-sized trees, reaching 10-25 m tall, rarely up to 40 m tall. The leaves are alternate, simple, 3-15 cm long, ovate-acuminate, and evenly serrated margins.
Small monoecious flowers appear in early spring while the leaves are still developing. Male flowers are longer and fuzzy. Female flowers are greenish and more rounded.
The fruit is a small drupe 6-10 mm diameter, edible in many species, with a dryish but sweet, sugary consistency, reminiscent of a date.
