Golden chain tree (Laburnum anagyroides
) is a small, upright, low-branched deciduous perennial tree or large shrub that is native to Europe. It is a popular garden and park ornamental in subtropical climates worldwide. It is notable for its profuse and showy late spring bloom of yellow flowers in dense, pendulous, wisteria-like racemes.
Golden Chain Tree Toxic Components
All parts of golden chain tree are highly poisonous, especially the seeds. The main toxin is cytisine, a quinolizidine, nicotine-like alkaloid that is found predominately in the flowers, seeds, and roots. Ingesting seeds in the amount of .05% per horse's body weight can be fatal.
