Okay first of all fuck off

Second of all: I would not say I associate Yao with a flower (except the peony but that's because a lot of ppl do so now I do as well) but I do associate him with the Ginkgo one of the oldest trees, which the leaf actually symbolizes longevity, with Yao being one of the oldest Ancients it just fits so well <3 his longevity being both a blessing and curse

For Julius it's the Chrysanthemum, because specifically in Italy it's associated with death, I did read that in other places it is a symbol of prosperity, festivity and joy which fits a lot with him
I am not too sure about a lot of info so I apologize if said anything wrong!
