Last year I took a cutting from a Hydrangea in my late Father-in-Laws
garden. The plant was a beautiful specimen and alwways produced a
wealth of
large deep-blue flowers.

My cutting rooted successfully and in spring I planted it in my
garden. It
has produced one large flower that is bright pink. Is this usual or
something to do with the different soils in each garden. (Or maybe
it's my
late Father-in-law having a last laugh)
