Remind me in the fall, Ted. I'll send you a cutting of the Monster. (it's too hot now) They root easily, and that one went from a 9in. cutting to a shrub 4ft tall and wide in one season. I have given starts to so many people it's a wonder it's not on the invasives list by now.
Once those brugs are in the biggest pots I can handle, I prune them back a bit after each time they bloom to keep the top growth a reasonable size, and that reduces the watering and fert demand, at least some. They are hungry, thirsty beasties.
