Buckthorn/Purging Buckthorn Seed

Purging Buckthorn is a large deciduous shrub or small tree. The spiny branches are very attractive in the autumn when they are carrying their small shiny dark almost black fruits and yellowing leaves. Flowers are insignificant yellow-green in summer and held close to the stems. Leaves and fruit are slightly toxic if ingested, causing stomach problems, though birds eat the berries with impunity. It is the food-plant of the Brimstone butterfly. In parts of N. America, this plant is classed as an invasive species, but this doesn’t happen here.
