Fabaceae - syn. Cytisus laburnum L., Laburnum vulgare Griseb., Laburnum laburnum Voss, Genista laburnum Krause;
golden chain, golden rain, Gemeiner Goldregen

Small deciduous tree or large shrubs up to 7 m, native to Europe.

„Spider mite-infested golden chain leaves emitted the induced compound (E,E)-α-farnesene in large amounts. The compound was also induced in mite-infested soybean, black locust, tobacco, hop, grapevine, and ginkgo. (E,E)-α-Farnesene has been found in the headspace of Psylla-infested pear, together with methyl salicylate (Scutareanu et al., 1997). Both compounds attracted anthocorid predators in an olfactometer. Because (E,E)-α-farnesene is present in large amounts in the volatile blend of golden chain it might be a defected compound for the predatory mites. However, for golden chain, it remains to be investigated whether spider-mite infestation results in attraction of predatory mites and whether (E,E)-α-farnesene plays a role in that.“

The shrubs usually planted in gardens are almost exclusively the hybrid laburnum (Laburnum × watereri 'Vossii' = L.anagyroides × L.alpinum), not Laburnum anagyroides (= L.vulgare).
„Due to the main alkaloids cytisine and N-methylcytisine, laburnin, laburnamin and chinolizidin alkaloids all parts of the plant must be regarded as toxic or highly harmful. In the fruits and seeds, the concentration is very high and increases steadily with seed maturity. Flowers contain much more of cytisin than the leaves. The young green fruits are reminiscent of pea or bean pods and seduce children to eat them. Poisoning symptoms occur already short time after consumption and resemble those of nicotine poisoning: nausea, dizziness, sweating, hallucinations, vomiting of blood, paralysis and collapse.“
