The various types of flower pots (empty or with a plant) still use the old 1.12 key item.flowerPot.name for the translation of their blocks (this can be seen in items with CanDestroy or CanPlaceOn tags), instead of the new ones (block.minecraft.flower_pot, block.minecraft.potted_dandelion etc.). The old key doesn't exist anymore in the translation files so it doesn't return any translation.

This issue doesn't affect the item form of flower pots, which correctly uses block.minecraft.flower_pot.

Steps to reproduce

• Issue

  /give @p minecraft:diamond_pickaxe{CanDestroy:["minecraft:potted_dandelion"]}
