Natalie,
I have no experience with these plants other then right now I have 3 seedlings in my greenhouse. I grew them from seed this winter and am currently debating on if I will plant them or give away. Lots of bad PR on these plants. On what I have read is the bloom cycle is short and the plant takes up a large space. Also read that when you plant them they grow there forever because they are hard to eradicate. The ones that I have seen around the PNW always look , well in my eyes, messy and unkempt. Not sure what cultivate your is sure hope an experienced person chimes in. By looking at the picture I would move away from the house. Your in Idaho, kind of hot there right now, so you may want to move in the spring.
