I saw a hydrangea which has a very deep blue flower with a white edge and veining.
I haven't been able to see this in anyone's list.
Unfortunately I didn't take a photo.
Does anybody have any idea as to which variety this might be



Could you be thinking of the 'Cityline Mars Hydrangea'? The depth of blue is related to the level of acidity. Acid=Blue, Alkaline=Pink. It can be altered with aluminum sulfide which you pick of at the garden center. Results won't show up for a year or two.

Do you mean a white edge to the blue petals, or a white edge on the leaves? And was it a mophead variety or a lacecap?

How do I say thanks?
