Yes, don't prune way the young shoots as these will have the flowers for the

Thanks. I don't actually plan to prune it at all, as I'd like it to
form part of a fencing hedge that's as dense as possible. I'm a bit
concerned that it hasn't flowered *at all* since I planted it a few
years back. It's in a really shaded part of the garden so I suppose
that could explain it somewhat.

I've got a Hydrangea as well, and that flowers abundantly even though
it's not really in full sun.
