'Pure and simple'

Thankyou fellow Blippers who welcomed me back a few days ago......I'm still not getting the time to comment, so I'm sorry about that. All of your photos are wonderful!

This Dog Rose seems to be growing out of the Apothecary White Rose...featured this week. I do love them but is it going to annihilate my Rosa Gallica Officinalis 'Alba'? Any ideas?
