We'd had one or two Skimmias in our garden for years, but they didn't thrive, and had hardly any berries. When I bought a male Skimmia to see if we'd get more berries, it died.
Last year I dug all three of them up, bought a new male Skimmia, and planted them all together, with lots of compost and bonemeal, in a place where they got shade all morning, but sun for a lot of the afternoon.
It seems to be working. But the odd thing is that even though it's October, the male Skimmia has flower buds opening. (You can just see some of them at the right edge of the picture). Maybe it's because we're having an odd sort of year. Even one of our rhododendrons that usually flowers in spring is blooming.
