Family: Papilionaceae
Common Name: Bean Tree, Golden Chain Tree

Originating from temperate regions of Europe and western Asia, this genus comprises two species of ornamental, deciduous trees grown for their attractive foliage, abundant sprays of yellow, spring flowers, followed by brown pods.

Species

L. anagyroides grows to 5 m (16 ft), with sprays of golden flowers in late spring to early summer. Cultivar 'Pendulum' is a weeping form. It is a long-lived tree, often trained over arches or pergolas. The timber is sometimes used as an ebony substitute in inlaid work. All parts of the plant are poisonous.

L. x watereri, golden chain tree, is a hybrid of L. alpinum and L. anagyroides, producing very long, drooping sprays of golden flowers. Cultivar 'Vossii' has even longer flower trusses.

Cultivation

Almost any soil will do, but these plants prefer full sun. They can be trained over pergolas and arches or on walls, and respond well to pruning in winter. Propagate species from seed and varieties and cultivars by grafting and budding onto stock species, or by layering.
