An evergreen Berberis, for a touch of purple all year lon. Thunderbolt, a new plant variety by INRAE, is a spiky shrub which resists well to the cold. Its broad shiny foliage keeps its red-brown colour; the milder the winter is, the more evergreen it stays. It has discrete golden yellow flowers in May.
How do you take care of a berberis?
Care. Evergreen or semi-evergreen varieties of berberis planted singly only need light pruning once a year to maintain their shape. If planted as formal hedges, berberis can be pruned twice a year. However, if pruned after flowering, shrubs will not produce berries, so if you want to keep the fruit, trim in winter.
