This deciduous shrub is displaying panicles of attractive flowers at the eastern end of Bateson Walk.
The ivory-flowered bladdernut, Staphylea colchica, has pinnate leaves with three or five ovate leaflets with finely toothed margins. In spring it produces terminal racemes of small, bell-shaped flowers. The fruits are a two or three-celled, inflated, papery capsule, hence the common name bladdernut. One of several species, S. colchica originates from the Caucasus. It was first introduced to British gardens in 1879. It will thrive in well-drained soil in full sun or partial shade.
