Okay I kinda made two more accounts just so I can redo what I did and actually wait for 50 flower gems rather than spend them like crazy. Here is what I got based on 4*+ units:
Alt 1: Convallaria, St. Paulia, and Cepha Lanthera
Alt 2: St. Paulia and Toad Lily
I'm kinda leaning towards alt. 1 has more higher rarity characters, but alt. 2 because it has two characters with quests atm. Any thoughts?

I also have another alt account that I was levelling up with my main account with Toad Lily, but like my main one, I did not save up to 50 gems before rolling gacha.
