Laburnum x watereri came from a cross between L. alpinum and L. anagyroides. The cultivar 'Vossii' of this cross has turned into the best known Laburnum. From a trunk height of approx. 1.5 m the main trunk often divides into a number of sturdy lateral branches. These grow in a spreading fashion producing a broad, vase-shaped crown. Crown width up to approx. 4 m. Young twigs are remarkably green. Branches and trunk turn brownish-green. The leaves are triple and each leaf segment is 2.5 - 7 cm long. Of all types and cultivars it produces the richest flowers, hanging in bunches sometimes up to 50 cm in length. The flowers are a deep golden yellow and have a slight scent. 'Vossii' forms fewer pods and less seed than other types: they are poisonous. The hybrid Laburnum x watereri also occurs in the wild. Laburnum x watereri 'Vossii' is one of the most eye-catching spring trees when in full bloom. The tree is also suitable as a trained tree or for making arches.
