"Q. What kind of ফুল is that on the cover, and what does it mean?
A. That is a ruffled tulip. As for the meaning... If you've read the Twilight FAQ, আপনি know that the আপেল cover had a lot of meaning for me, and I was an active part of the covering process. However, that experience is আরো the exception than the rule in the publishing world. Something to keep in mind if আপনি intend to embark on a career as a writer: lots of things আপনি might expect to be under your control are not. Covers, for example. Those are mostly up to the publisher and the marketing and sales departments. So I don't know what the ঘণ্টাকর্ণ means—I didn't have anything to do with this one."
আপনি can find it under Twilight Series > New Moon > FAQ. Hope I helped :P
Lot's of people have different opinions on this, but I believe that the ফুল represents Bella's heart. Why? Because I think that it's red because she's hurt inside, and the white represents a little bit of hope/love that's still there. However there's a petal dropping off because she feels as if she's falling apart. But, that's just my view, most people's are different.
There are sites that say the ফুল has absolutely no meaning seeing as Stephanie Meyer did not choose the cover for New Moon. Then there are some sites that say the ruffled ঘণ্টাকর্ণ represents a beautiful প্রজাপতি coming into view. I'm not sure which one is true, but that's all I could find. (:
I believe that the this ফুল fades, and it represents as she feels Bella when Edward goes away, but for it me represents sinceBella's হৃদয় is in this book, the white thing represents the cold (is Edward) and the red thing is the heat in this case he would be Jacob.
To Stephenie Meyer, the ফুল doesn't have any meaning. But I personally think the tied in red and white shows Jacob coming into her life. The answer is basically up to you.
