Not a ship but i've seen ppl headcanon her as xin hua as her sister

Flower x lily, just bc of the names maybe XD

.... this is awkward considering the other comment but umm.. flower x xin hua... I ADORE THEM, they look so cute together no matter the design & in my au theyre dating and they take care of the meikas together. i call their ship flower squared sometimes..

Besides them, flower x lily's also cute i used to ship it, as well as flower x miku, flower x yukari, and flower x yohio

I mean they aren't canonically siblings so it's not too weird lol. i've seen some xin hua and xia yu yao (chinese utau?) shipped together too
