Barberry - Berberis thunbergii - Shrub
A large group of deciduous shrubs that have a wide variety of attractions. Some have ornamental foliage, others wonderful autumnal colour, some flower beautifully and others produce decorative berries.
What they do all have in common is that they have spines that are often hidden just below the leaves. As well as their horticultural attractions, they therefore also are excellent as plants for enhancing security around a property, either as a hedge or as individual or groups of plants under vulnerable downstairs windows preventing access. The spines are small and not often immediately obvious, they are however very vicious.
They make good additions to a mixed border or can be used to provide a very attractive and effective mixed hedge. I have planted several ornamental security hedges made of a mixture of Berberis and Pyracantha varieties.
