Currently, Purslane is my only 6 star Flower knight and I'm having trouble getting 5 and 6 stars from the gacha.
Flower gems are more common around the 1st and 2nd stages of events but after that they become hard to find. and I've also completed all of the stages on the 4th quest tab.
were you playing at Nutaku or at DMM website?
DMM is quite generous in giving flower gems to players while the Nutaku version is quite a feat. But doing event will net you flower gems. Just rinse and repeat until you reach the necessary amount. Also, You are quite lucky to get a 6* already, I have been playing Flower knight for 6 months and there is still no sign of a 6* coming to me.
He is playing on DMM as nutaku doesn't have the 4th tab.
Eh, except from logins and affection you'll have to run maps and 3* them but you definitely get more passively here
