Plant identification No. 2 please
I took this photo at the beginning of May and this is the only photo of the plant with any form of flower that isn't out of focus.
This is a plant that I came across in the garden, but I didn't realise it was a separate plant as it was hidden by the surrounding shrubbery.
It is growing in a south facing aspect.
Does anybody have any ideas of what it might be. I realise it might be a challenge as the buds aren't even open but any help would be appreciated.
