I remember Ruth or Hugh Cocker (no "r") telling me once that they had some similar seedlings to Dots and Dashs out of that batch of siblings. But I think Dots and Dashs is the only one they named. Ramona, did it have a name, or could it have just been numbered? Some of Cocker's clones that are only numbered are in circulation here at the epicenter.
I used to have one that had white and green variegated leaves in the spring that was from them. But it was just a novelty, a pretty weak grower and not very showy.
We've made a huge expansion of the lily beds at Arneson Park here in Minneapolis to house Minnnesota bred Lilium cultivars. If you come to the National convention in 2014, it will be on the tour lists.
