I have 2 of these, both planted in shade and previously very dark green and glossy.
One of them has started to go rather yellow though - is this because I haven't made the soil acid enough, or something else? The other one is still glossy green and only a foot away, but one leaf is starting to turn yellow on it.
Also, although both produce glorious white flower panicles in Spring, the berries that come from them are pitiful - never usually more than a smattering at a time, maybe 5 per plant (and these are 3 year old plants).
Do they need to be male and female planted together for there to be berries or is something else not quite right?
