Hi Laurie is such a member and so am I. It looks very much like Helen Collingwood (K.Smith,1949)38"tall, blooms ML season. A superb neglecta, very nearly an amoena, Very pale lavender standards with brilliant purple falls. Won the AM award in 1952.

Another possibilty might be Cape Cod (Knowlton,1951) TB White and red-purple bicolor. but I am thinking it is most likely Helen. I have not seen Cape Cod in person but grow Helen Collingwood. Unfortunately my pics are not facing the right way but you can look at them.
