Answer: You didn't buy Chipman Red, explains Dale Marshall, USDA rhubarb expert at Michigan State University in East Lansing. Stalk color is dependent solely on the genetics of the variety. Chipman Red is the reddest rhubarb variety available. If your variety is solid green, it was probably mislabeled. You likely received MacDonald or some other green variety, he says. Order Chipman Red from another company or ask your original supplier to replace the plant.
