I was in Christchurch recently for a family event and saw this plant – well I smelled it first. It is Skimmia japonica, a very attractive shrub with these fragrant flowers and handsome foliage. Sounds as though it might grow in the north so I will try some cuttings. I have never seen it for sale up here. This plant might have bright red berries in the autumn. Although some skimmias are hermaphrodite others are dioecious – separate male and female – and need both present to set berries.
