I don't have specific ideas on that, so probably the species that I can't recognize that are on her gun in term of aesthetics maybe?
She also doesn't seem the type to pay attention to flower symbolism in gen (tho I can see the devs maybe implying something to the players via the ones on her gun) as long it looks pretty & she get roses for a romantic date.
I hc tho she's the one who picked the low-poly flowers in Rufus's room you can find in one of the old AC trailers to bring some life & color in his lodge because it's sooo empty & she remembered that he had flowers on his coins, which make her conclude he likes flowers in general.
