Laburnum (Laburnum anagyroides) Identification

Laburnum / Spring / Summer / Autumn / Toxic

Laburnum is a fairly common sight in parks and gardens especially in spring when they are in flower.

Although it looks absolutely beautiful when it comes into flower all parts of this plant are toxic so it’s an important species for foragers to be aware of. I actually talked to a friend once who runs a nursery at their hourse and they had to have it removed from their garden due to the risk to children.
