Got a decklist from here a while ago when master duel was released, modified it slightly through some games.
Always always always start with Rikka Petal. Use your Lonefire Blossoms, Rikka Glamour, and One for One to bring it out ASAP. Use it to search for Snowdrop if you have another plant in your hand, especially good if you have two plants; one being Rose Girl or Primula.
Use Snowdrop to tribute the Rikka Petal, targeting a plant that isn't Rose Girl or Primula. One of those two cards will Special Summon itself when Rikka Petal is tributed.
