Betsy,
I think it's safe to say that you will be able to find all sorts of 'hard to grow' and 'easy to grow' lists. When considering something new, pay attention to the recommended conditions. The 'difficult' list you mention above also has 'June' and 'Fire and Ice' on it. But, I have no problems growing either one. Go with what you like and see what happens. Besides, part of gardening is you working together with the plants to keep them happy and healthy.
