Minecraft wiki entry for Flower, associated text: In Bedrock Edition, when bone meal is applied to any single high flower (except wither roses) that has been placed or generated on top of a grass block, more flowers appear around it without grass. With the exception of dandelions and poppies, the flowers that form around are the same type as the original flower. In the case of dandelions, poppies occasionally appear, and vice versa for poppies. The flowers can appear up to 3 blocks away from the original, forming a 7×7 square.
