I have a question for everyone about the height of 'Dr. Merkeley'. The description here on HMF, which is attributed to Skinner's catalog, gives a height of 2'. I received a sucker of what is supposed to 'Dr. Merkeley', but the mother plant is about 6' tall. Does this mean that what I have is not 'Dr. Merkeley', or is it possible that it gets taller when grown south of Winnipeg?
