It's time to introduce myself to the plants I already have in the garden and have been immediately drawn to those which have 'winter interest'. So I think we have:
Mahonia beale Pynaert
Viburnum tinus
Santolina decumbens
This is good - I can add them to my plan. It's still freezing out there so using time to clean the greenhouse, make some supports out of odd branches I am finding scattered around the garden, identifying plants and measuring up.
