Abelia 'Kaleidoscope'.
Like Hebe Pretty n Pink posted above, Kaleidoscope is a modern variety of Abelia.
Abelia Grandiflora / Grandaflora nana are best known for their speed of growth and hardiness. That said, they tend to be a boring green plant.
Kaleidoscope on the other hand improves on the original by adding vivid golden yellows, lime greens and red tones depending on the season. It has a compact growth habit with a height and spread on 70cm x 90cm. It will tolerate some drought but in my experience, regular water over summer will keep them looking great. Abelia 'Kaleidoscope' can planted as a small hedge, a colourful gap filler and also looks great planted into pots.
