Paeonia

Paeonia is a flower originally planned for implementation in Java Edition 1.7.2, but got replaced with the peony.

Paeonias would presumably have been obtainable through similar methods to other flowers. The only released screenshot depicts them planted in a taiga biome, though as peony bushes have never generated in this biome it is unknown if they would have naturally generated here.

Paeonias would presumably have been craftable into pink dye like the peony bushes that replaced them, and would have had the same properties that are shared by all one block tall flowers.
