I was hoping someone would just recognise it
I did forget to mention that is is a tree though. It is a small trees that starts of looking a bit shrubby. It ends up about 3 m tall with a single trunk.
The berries are single and produced from each flower. I don't know about seeds but there is definitely not a large pip in the middle.
If no one knows I will have to wait until summer to get a picture of the fruit because they are more distinctive and last longer than the flowers.
