Hidcote or St. John’s Wort Hypericum, is a maintenance free shrub you can prune in early spring. Hypericum is a genus of almost 500 plants. In some locations such as farms the plant is even considered a weed. St John’s Wort has also been used in medicine and herbalism as antidepressant. The flowers are yellow and it is a deciduous shrub that grows well in sun or partial shade. I came across this Hypericum while walking through one of the city parks in London.
