I was skeptical at first, but in reading your explanation I think I can definitely see the point you're making. Your last sentence, especially, makes sense with Snape's character. I also liked your point about how when his character was finally developed (or in the flower metaphor, well nurtured), we were able to see his most beautiful state (blooming). That was what really swayed me to see it your way.
