The drooping panicles of the bladdernut, Staphylea holocarpa 'Rosea', bring welcome spring interest to the Rose Garden.
There are 11 species of the deciduous, temperate genus Staphylea. All have bell-shaped flowers, borne in panicles. Each species bears two or three fruits, which develop into an inflated, papery bladder, hence the common name. The straight species, Staphylea holocarpa, has white or pink-tinged flowers. It occurs in central and western China, from whence it was introduced by Ernest Wilson, who considered it to be the most beautiful of the genus. The selection 'Rosea' has pink-flushed flowers.
