Well done on the toms
My dwarf beans (speedy) flowered while they were still really short, I think they were a bit taller than 8" though, more like a foot? They have grown a bit taller since then, and we have beans on them, but they are still not much taller than a foot or so. I sort of assumed this was normal lol
My other dwarf beans (delinel, and another I can't remember what it is) aren't in flower yet.
