Laburnums are flowering magnificently at the moment. The flowers seemed rather brief and sparse on this one last year, probably another instance of variable weather having an effect.

 All parts of the tree are toxic to humans including the pea-like seed pods and there have been some scare stories in the past. The two species L. anagyroides  and L. alpinum are of the Pea family Fabaceae but not all peas are edible. Moral of the tale: look at Laburnums, don't eat them.

 Note the bumblebee moving in to forage. Laburnums are a magnet for bumblebees so it would appear their metabolisms experience no ill effect.
