Azalea Leaves form the canopy of azalea trees that generate on the surface above lush caves in Minecraft. The plain leaves have no pink blossoms, unlike Flowering Azalea Leaves. Players can collect Azalea Leaves with shears or a Silk Touch tool; breaking the foliage normally can drop azalea bushes and sticks. Naturally generated azalea trees stand above rooted dirt that leads downward toward the lush cave, so the tree is a useful exploration marker rather than proof that every placed azalea tree has a cave beneath it.

Azalea Leaves work well in garden hedges, overgrown ruins, greenhouse roofs, and custom trees because their green texture stays visually distinct from common oak foliage. Player-grown azalea trees come from applying bone meal to an azalea or flowering azalea bush on dirt-type blocks, but growing a tree does not create a lush cave. Azalea Leaves decay when no longer supported by nearby wood unless the foliage was placed by a player, so builders should harvest the canopy before removing the oak logs.
