Well, I do agree that 10 months sounded extreme, but they did the research over a 12 year period I think it stated, so I just accepted that. The main thing I took away from the article was to look for a bloom time of 60 to 90 percent of the bloom cycle from great performers. So here (zone 8b) I should expect to get 30 to 60 days of blooms pretty consistently I would think on a very conservative estimate..
