MR,
Some of the crosses with 'Silverine' were hand crosses but I raised a large group of bee set seed from a plant that was adjacent to 'Cleveland Morgan', 'Rubrum Borsch', and calcareum. All three crossed onto the 'Silverine' plant and passed on different traits. 'Silverine' has wulfenii in it so it will give very broad leaves and the lotus form to its seedlings. 'Silvertone' is a cross of 'Silverine' and 'Purdy's 50-5'.
This year I self-pollinated a stalk of 'Silver Song', which was the widest leaved plant of the group, to see if it will give exceptional width. 'Minaret' was the bluest of the 'Silverine' seedlings and it gave rise to the very blue 'Frost and Flame'. A cross of 'Frost and Flame' X 'Pacific Blue Ice' gave some very blue seedlings, perhaps the bluest I've seen. It is fun to finally be able to take these lines to their logical progression after my long hiatus.
