Origin Grass can only be found in the Origin Island biome, and has the appearance of the grass blocks found in Classic versions of Minecraft.

Unlike normally occurring grass blocks, Origin grass blocks do not change color in different biomes and do not respond to bonemeal.

It is also not possible to put Biomes O' Plenty flowers and grasses on origin grass, although it is possible to place all saplings and some Vanilla plants like roses and ferns. Sugar cane can be placed and grown on this block even if it is not adjacent to water, making it useful for paper farms. Also, sheep without their wool can't eat this kind of grass, making it useless for wool farms.
