- Description
-
Hackberry is a deciduous tree native to North Carolina that commonly grows to 40 to 60 feet in height and 1 to 2 feet in diameter, but on the best sites, may reach a height of 130 feet and a diameter of 4 feet or more. It has a straight central trunk and an ovoid crown with a cylindrical shape once mature. It can be sparsely found throughout the state, though not in the high mountains. It is most abundant and reaches its maximum size on the rich alluvial lands in the lower part of the state, but it can survive and grow in most types of soil from the poorest to the richest.
It is best grown in moist, organically rich, well-drained soils in full sun and can be transplanted easily. It will tolerate part shade, wind, and many urban pollutants, but does not do well with maritime exposure. The wood is heavy, rather soft and weak. It decays quickly when exposed to moisture. The branches can tend to droop. These trees can live 150 to 200 years.
This tree makes a perfect addition near your butterfly garden, as it is a host plant for the larvae of several butterflies, including the American snout (Libytheana carinenta), Mourning cloak (Nymphalis antiopa), Hackberry emperor (Asterocampa celtis), Tawny emperor (Asterocampa clyton), and the Question Mark (Polygonia interrogationis).
Insects, Diseases, or Other Plant Problems: Watch for Asian wooly hackberry aphid, lacebugs, and scale. Witches’ broom (creating dwarfed, dense, contorted twig clusters at the branch ends) is somewhat common; while it does little harm to the tree but can be quite unsightly. Hackberry nipple gall also does not hurt the tree but can disfigure the leaves. Powdery mildew, leaf spot and root rot may occur. Seeds can pose clean up problems if trees are sited near sidewalks or patios.

- Wildlife Value:
- This plant supports Hackberry Emperor (Asterocampa celtis) and Question Mark Butterfly (Polygonia interrogationis) larvae. Questionmark butterflies have an interesting life cycles: overwintered adult Question Mark butterflies lay eggs from spring until the end of May. These will appear as summer adults from May-September, laying eggs that then develop into the winter adult form. The winter adults appear in late August and shelter for the winter starting the cycle all over again. Adult Question Mark butterflies feed on rotting fruit, tree sap, dung, and carrion only visiting flowers for feeding when absolutely necessary. Also a host plant for the American Snout, Mourning Cloak and Tawny Emperor butterflies. The fruits provide food source for many birds and small mammals. It also provides cover and nesting for birds. Cover is also provided for game birds, rabbits, and deer by the young stands.

- Insignificant, mostly monoecious, greenish flowers appear in spring (April–May) with male flowers in clusters and female flowers solitary. Regardless of type, flowers are about ¼ inch across and predominately yellowish green; each flower has 4 to 5 oblong sepals connected together at the base. Male flowers also have 4 to 5 stamens with yellowish brown anthers, while female flowers have a green superior ovary that is ovoid in shape and tapers into 2 beaks. Originating from these beaks, is a pair of large brownish stigmata. Individual perfect flowers have both a superior ovary with a pair of stigmata and 4-5 stamens.
