Noteworthy Characteristics
Staphylea pinnata, commonly called European bladdernut, is a deciduous suckering shrub that typically grows to 10-15' tall. It is native to southern Europe, Turkey and the Caucasus. Compound pinnate leaves with 5-7 pointed, ovate-oblong leaflets (each to 4" long) are medium green. Small, fragrant, bell-shaped, white flowers (each to 1/2" long) with red-tipped sepals bloom in drooping panicles (each to 5" long) in late spring. Fruit is an inflated, papery, baggy, 2-3 lobed, subglobose seed capsule (to 1 1/2" long). Seed capsule is often described as being "bladder-like" in appearance, hence the common name of bladdernut for this shrub.
Genus name comes from the Greek name staphyle meaning a cluster from the arrangement of the flowers.
Specific epithet refers to the pinnate leaves.
Problems
No serious insect or disease problems. Leaf spot and twig blight may occur.
Uses
