Berberis x media 'Red Jewel' could just as easily have been christened 'Rainbow', for its semi-evergreen, bronze-red foliage turns a green colour, followed by a dark purple, as the season progresses. The hardy shrub's changing palette is complemented by pastel yellow flowers in the spring and vivid, red berries in the autumn. This Barberry is practical as well as pretty, for its dense, rounded habit makes for a great, prickly hedge. Height: 2m (6'7); Spread: 2.5m (8'2).
