Thank you so much for the very quick replies. i hate throwing plants away, in fact i often buy plants when they are reduced just because i feel sorry for them.
and Dovefromabove, i already have a beautiful blue hydrangea which was already in the garden when i moved here. so maybe i will try a pink one next.
someone further up the street has one which has a mixture of blue and pink flowers, don't know how as i thought the colour was decided by whether the soil was acid or alkaline.
