A really striking shrub, notable not just for the acid yellow flowers, but also for the dark green foliage and, once the leaves drop in autumn, the rich lustrous black-green stems (a bit like the black bamboo, as my mate Richard pointed out the other day).
Hardy and adaptable but probably at its best with some shelter. Other members of this group (Laburnum, brooms etc) are real sun lovers, but Piptanthus nepalensis can look a little washed-out in too much heat and drought. It often looks its best in less exposed, cooler, and even semi-shady conditions.
Can be grown as a free-standing multi-stemmed shrub or trained on a wall.
