A lovely new Clematis was launched at Chelsea by Thorncroft and the good news, it's scented.
Clematis SUGAR SWEET™ BLUE 'Scented Clem' is early flowering in April and May. It has pretty violet blue flowers and said to have an almond scent, more pronounced early morning and evening.
Given its flowering time, I am assuming it is a group 1 which means little or no pruning and so one of the easier Clematis to grow.
If you want to try something new for next year take a look details on Thorncroft website.
