They are large shrubs, occasionally small trees, growing to 2–5 m tall. The leaves are deciduous, arranged in opposite pairs, and pinnate, usually with three leaflets, but 76–178 mm (3–7 in) S. pinnata and 76–127 mm (3–5 in) S. colchica. The flowers are produced in drooping terminal panicles 5–10 cm long, with 5–15 flowers on each panicle; the individual flowers are about 1 cm long, with the five sepals and petals similar in size and in their white or pale pink colour. The fruit is an inflated papery two- or three-lobed capsule 3–10 cm long, containing a few small nut-like seeds.

Cultivation and uses

Several species are grown as ornamental plants for their flowers and peculiar bladder-like fruit. The popular Staphylea × elegans is a hybrid of unknown origin, probably between S. colchica and S. pinnata.
