This hardy shrub is popular for its late winter and early spring blossom and its all round reliability. If it is yellow you are after then you cant go far wrong with Kerria. Whether in full sun or part shade and on a variety of soils Kerria delivers an early splash of blossom, but then looks rather mundane for the remainder of the year.

Cultivation tips: Kerria makes a decent upright screening shrub, possibly as part of informal shrub planting. Ideally Kerria is planted towards the back of the border where it can do its yellowy business with its spring blossom only to be allowed to take a step back during the spring and summer, as this shrubs habit can be scruffy looking and the foliage is rather un-interesting.
