What kind of smell did edward say Bella posessed?

Answer 1

From a Midnight Sun chapter (Edward's perspective) he says:

''Bella Swan walked into the flow of the heated air that blew toward me from the vent.

Her scent hit me like wrecking ball, like a battering ram. There was no image violent enough to encapsulate the force of what happened to me in that moment.

In that instant, I was nothing close to the human I'd once been; no trace of the shreds of humanity I'd managed to cloak myself in remained.

I was a predator. She was my prey. There was nothing else in the whole world but that truth.

There was no room full of witnesses - they were already collateral damage in my head. The mystery of her thoughts was forgotten. Her thoughts meant nothing, for she would not go on thinking them much longer.

I was a vampire, and she had the sweetest blood I'd smell in eighty years.''

Answer 2

Edward described Bella as having the scent of freesia, a flower with a sweet and fresh aroma. This scent was particularly appealing to Edward as a vampire because it contrasted with the typical scent of human blood, making Bella all the more enticing to him.
