Tree identification help please

I would like to identify a tree which is flowering at the moment (it may be a very large shrub). I don't have a pic unfortunately, because I've been driving at the time that I've seen them.

It has what appears from a distance to be bronze new leaves coming through, and magenta flowers and it looks stunning.

Any ideas please?

 

Maybe Prunus cerasifera nigra???

Thanks for the suggestion but I don't think it's that - the flowers are more magenta.

Actually I've just Googled 'tree magenta flowers' and it may well be some sort of flowering crab apple.

Will have to take a photo of one which is near the office.

 

Hmm! How about Malus Cardinal.

Could very well be that one - I'll get some pics of one and post for more advice.

Thanks for your help
