Thank you, Mike - digitizing all those pictures was a lot of work, but very interesting. Unless a person grows masses of flowers from seed, one never sees the range of variation that is possible. Usually, the grower chooses a couple of favourites, and that is all that the rest of us see. Maybe we all would have chosen differently. You mention a number of times that you are selecting for flowers arranged radially. This is a good idea for a garden plant, as so often one-sided flower heads resolutely turn their backs on the viewer, no matter which way they get planted. -- Diane Whitehead Victoria, British Columbia, Canada maritime zone 8 cool mediterranean climate (dry summer, rainy winter - 68 cm annually) sandy soil
