I don't know if this is the right place to ask this, but I just started playing this game again recently (I first played it almost a year ago, and just the tutorial). I still feel like I know very little about the game (I just realized there were 6 stars today browsing the forum). So, my main questions are as follows:

Are the following 5 stars any good: Candlebark, Texas Bluebell, Dogwood (Yukata), Kiwi, Japanese Parsley, Creeping Saxifrage, and Chickweed

Once I beat all of the event stages, what is there to do with an event?

What should I be saving my flower gems for?
