Sweet!
They are so pretty.
I didn't know that a cross between an F1 and an OP was also called an "F1". I did a couple of this type of complex cross this year but ended up labelling the seeds "F2", because I know they'll be all over the map, not uniformly identical like the usual F1 hybrid.
Crosses between F2 and OP I also labelled F2.
Confusing... yes.
Good to hear you have lots of space for your growout.
