That's really beautiful! Love, love, LOVE those colors!
I think I'd have to make the blocks one at a time if I were going to try to make each leaf of one fabric, like this. Between the ADD and the lack of patience with things that need to be ripped out and re-sewn, I'd be frustrated at trying to keep it all correctly oriented.
As with the indigo quilt, I would go for a scrappy look. No tears or pulling my hair out while I'm piecing
and you can chain-piece the patches and blocks. No worrying about which way the wings are going.
