Normally prior to this game it would probably be Carnation and Lillies. but mums look great and Cosmos have found their way into my heart after getting them as a native flower
Mums, Hyacinths, and...windflowers? Not sure about 3rd place, since I haven't even seen roses, cosmos or lilies yet
I'm still a bit sad that the violets didn't make it into the game, since I love blue/purple flowers. Thankfully, a lot of the other types come in those shades too, so at least there's that.
I still haven’t seen tulips, roses, or lilies, so I’m just lucky that my island has hyacinths with pansies as a secondary and my boyfriend’s town has cosmos.
