Biomes O' Plenty Wiki

The Flowering Oak Tree is a tree that can be found in the Rainforest biome. It has a mix of both vanilla oak leaves and flowering oak leaves, which have a distinct texture. Only the flowering leaves drop flowering oak saplings. As of BOP 2.1.0, a possible glitch exists in where profusely using bonemeal on a flowering oak sapling will convert it to a Sacred Oak sapling.
