Yes, and I know you didn't ask for more on hardiness, but I can't stress enough how important it is. Because under that topic comes a whole lot of things like a plants resistance and tolerance to diseases and pathogens, both below and above ground, how adaptable a plant is to a variety of climate, weather and soil conditions and so on. In other words, you want a plant that not only looks good, but will grow just about anywhere and live a long time with minimum care. Selecting good strong hardy parents in breeding is very important because when a low resistance to something like botrytis is allowed into a bloodline, it is next to impossible to breed back out.
