Pam - Thanks for your suggestion that it might be one of those seedlings that produce BOTH singles and doubles on it's scapes! I don't know why that did not enter my mind at the moment I posted the question. Duh.
Ashton - Looks like the party is in YOUR yard! Look at all those gorgeous seedling blooms! Makes me pine for more land to grow more seedlings! They are all wonderful! I really like that last one you just posted! Very nice, indeed! 8 1/2" bloom is quite impressive, too!
