The timber of Laburnum is highly valued in cabinet making and woodturning. The whole tree is highly poisonous. It contains cytisine, and if consumed by humans and other animals it can be extremely toxic, although other animals like hares and deer seem to cope well with it and are unharmed when eating the seeds.
