Introducing Rhamnus cathartica, commonly known as Buckthorn, Common Buckthorn or Purging Buckthorn. This deciduous shrub/tree is native to Europe, northwest Africa, and western Asia with grey-brown bark and often spiny branches. The small black drupe fruit contains two to four seeds and is popular with birds but mildly poisonous for people and animals. The bark and fruit have been used as a purgative in the past, however, their potentially dangerous side effects means they are seldomly used. Often grown as an informal hedge, it is also amenable to trimming. The wood of this handsome plant is hard with a marble-like grain and used for small turnery. Not just useful in nature, a green pigment used in watercolour painting is made from the immature fruit mixed with gum arabic and limewater. Yellow, orange and brownish dyes can also be obtained from this versatile plant. So whether you're an artist, gardener, or woodworker, this remarkable plant has something to offer.
