I've struggled with this for a while for the reasons you've mentioned Chelle. Even going to the best sellers sites basic exposure information never tells the whole story. Hopefully greater detail is available. The issue as I see it is so intertwined with local climate that a more than short blurb explanation is generally required. "Afternoon shade"? where is the grower located? This is why I try to remember to always add my hardiness zone and location when posting a comment.
