Blue hydrangea

I realise that my recent blips have all had a birthday/anniversary/horticultural theme going on; well, today is no exception. This potted hydrangea was one of the plants used to decorate David's blue-themed 40th birthday party last week - you can just see it peeking out on the LH side in this picture. Mum has been lovingly tending it for weeks and today very kindly said I could have it as a reminder of the birthday and its blue theme - now I just need to decide where to plant it!
