A rose link is a disjoint union of a finite number of unknots. Each unknot is considered a component of the link. We study rotationally symmetric rose links, those that can be rotated in a way that does not change their appearance or true form. Brown used link invariants to classify 3-component rose links; we categorize 4-component rose links using the HOMFLY polynomial.
