I've got a big Sarcococca Buxaceae in pot by the front door and the smell is wonderful. I've never heard of your one, Badgerwatcher, is that a new variety?
There is a witch hazel in the back garden which has been smothered in flowers since mid December, which is heavenly too. On the few mild sunny days we have had there have been quite a few flying creepy crawlies on that so it is one I would recommend for this time of year.
I am sure Jaki (Garden Carpet) will tell you what a draw for insect life her plum tree is - she gets so many
Red Admirals nectaring on them, the lucky sausage! The birds will love the cherries too.
All round I think you have made some good choices there.
