I grow Big Time Happy in MI after buying a potted plant. Clumps rapidly...It has only been in-ground one year in 2021 and had 8 fans with 7 intial scapes+rebloom. Bud count low at 9 so far but with so many scapes it's not that noticeable. Taller and larger than 'Happy Returns' so good for us old folk
Pod fertile for sure/readily "bee" pods. I have crossed with a taller, gold NoID with 1st seedling blooms expected 2022. FFO 6 July in 2021 makes it early mid-season. [just about everyihing I have FFO's in July so it's hard to be certain.
] plus rebloom had flowers into October.
