Every year we buy a lot of dahlias which duly flower in the colours shown on the packet.
Every year we dig them up to stop them freezing and store them in a dry dark place.
Every year we replant them.
And every year they flower again. And they're all white! No more yellows, reds, oranges -- just white.
Is this just a normal ploy to keep us buying new dahlias or are we missing something?
