flowers changing colour
I have planted a variety of plants in clay soil which have changed colour from the expected/original red to pink i.e Lupin Red Castle, Achillia red, and a miniture rose which was red in one bed and has now turned pink when I moved it. Also a dahlia that was purple has now gone a blush pinky colour. However the cosmos I planted have come out as they should and are in the same bed. Any ideas what could be happening here?
