Evan,
I want the Chumley Curly in my crosses for added leaf interest and for greater cold resistance. Mature Chumley Curlies are smaller than mature P. bipinnatifidum plants, but not near "miniature" size. I'd say, 3 to 4 feet in diameter vs. 6 or more feet in diameter for regular P. bipinnatifidum. My Coral Gables dwarf hybrids are smaller than a Chumley Curly - I'd love to cross one of them directly with a Chumley Curly. That's one reason I'm trying to get a Chumley Curly to drop back out of an F3 or F4 hybrid with the CC in pedigree.
