Corokia x virgata
Random would be the most obvious word to describe the habit of this unusual evergreen shrub from New Zealand. Grows to 5ft after about 6 years and has copious quantities of little yellow flowers in summer.
The branches twist and turn but the plant can be clipped to any shape yet retain its twisty turny look.
Any reasonably well drained soil but plenty of light.
Propagated by us from cuttings.
