Another white bloom

I dont know what this shrub is called. Its been here as long as we have. But it shows its whiteness so well and lasts a good while.

Off we went to Cambridge's edge of town shopping centre. We went in many of the shops, looked at lots of things, got some ideas but bought little. We did come home with 4 Lidl almond croissants and some more chocolate. Got to keep shopping supplies up.
