Just an update now that two more seedlings have bloomed! I don't think that they help make a determination as to parentage though but I thought I'd show them anyway. There is still another seedling that still hasn't bloomed (maybe next year?).
Seedling #10-looks exactly like the pollen parent but blooms earlier.
Seedling #11-another bitone! This is its first flower ever so the color may change a bit.
