I bought a Glaskins Perpetual Rhubarb plant from a Nursery to go with the other 4 varieties that I grow on my allotment. It is probably about 3 years old now and each year I wait for the stems to go red. They are green and the only time that they are red is when they die. SWMBO questions whether it is edible. It is a total contrast to my other varieties. It cannot be its situation as the Champagne next to it is OK.
I shall be interested in any thoughts/experiences.
