Hi, fell for this coreopsis at the garden centre. Photo doesn't do it justice. It's the most gorgeous autumnal dark red. Can you tell me if it is unadvisable to plant it in my clay soil. Would it be better off in a pot in my border and if so how my grit should I mix in?
if it can go in the ground, ought I wait til spring to plant?
