Ostrya carpinifolia is a deciduous tree with a rounded habit. Its foliage is oval, glossy and dark green in colour, turning yellow in autumn. It bears dioecious yellow catkins in mid spring with the males being slightly longer than the females, which are followed by hop like greenish fruit clusters that become brown in autumn.

O. carpinifolia, commonly known as the Hop Hornbeam is native to southern Europe and  western Asia. It has been traditionally used for carpentry due to the tough, close grained nature of its wood. It is also a popular source of wood for charcoal.

Ostrya is derived from the Greek ostrua, meaning bone-like which refers to its hard wood. Carpinifolia alludes to this plant having leaves like those of the Carpinus or Hornbeam.
