Laburnum × watereri

Laburnum × watereri (or Laburnum watereri), is a naturally occurring hybrid species of Laburnum, native to Central Europe. Its parents are common laburnum, Laburnum anagyroides, and alpine laburnum, Laburnum alpinum. A small deciduous tree or large shrub, it is a popular garden plant, called golden chain tree for its spectacular display of hanging clusters of yellow pea-like blossoms.[2] It can be trained to take forms such as arches and espaliers.
