I adore the name Leilani which mean "Heavenly Blossum" so in some ways you kill two birds with one stone - an L name and a flower
I really like the name Leilani but I find it to be a bit if a mouthful, how about Delanie (meaning: 'from the alder grove')?

I really like Olive and Poppy, I also love the name Annie-Mae.
