Spacecoast Chomp! Chomp! hardy E Central Wi, zone 5a, bought in 2017, almost impossible to set a pod on here, pollen is very fertile for me thrips have been a problem.
I also grow Bonibrae Witches and Warlocks, similar look, sets pods easier, no thrip damage, pollen just as fertile with more branching and a higher bud count.
Bloom size is similar here for both, SC Chomp! Chomp! a tad taller,
Plant comparisons are from my yard only, both plants were purchased in 2017
I'd recommend Bonibrae Witches and Warlocks based on my experience, I have not bloomed any kids from either.
