Thomas: color depends on the 'type' of plant. Victoria Red is more red stalks and a l little less tart than the green. As far as cooking the rhubarb is concerned: it doesn't matter. From what I read- I don't think the sand is a good idea, as all rhubarb needs the feed/nutrients. Maybe you could add some darker soil--miracle grow organic--to your soil?
