What a glorious Morning Glory Vine! I don't think I've ever seen an MG so lush! Your first photo is really nice showing the entire plant and since the only photo in the database of Scarlett O'hara is a single bloom, I've proposed to move your photo over to the database.
Japanese Morning Glory (Ipomoea nil 'Scarlett O'Hara')
I agree with Chelle that you should try some *Bloom Booster* plant food and see if that helps.
