They will get pretty good size Patty, but this one is next to the greenhouse, where it is protected (also our winters have been very mild), and has been coming back each spring.

I have seed for one called giant castor bean that got 15' tall last year. It did not freeze last winter, but I ended up cutting it down anyway this year because it had a bumper crop of seed and I didn't want them popping up all over my place.
