At the moment:
The lush flower band is white, orange and purple, and has no recipe.
The exotic flower band is white, orange, purple and pink. Its crafted with clover, orange cosmos and violets only.

The exotic flower band seems to have the recipe meant for the lush flower band, and the exotic flower band recipe, which wikis indicate use to also include Pink Daffodils, is missing.
