Jungle Grass Seeds

The Jungle Grass Seeds are a type of Seeds that can be planted in Mud Blocks to grow Jungle Grass, for creating an artificial Underground Jungle or Jungle, depending on the depth. Seeds can be found by cutting grass in jungle environments using any tool or weapon.

Like a natural one, an artificial jungle will become inhabited with the respective enemies. Snatchers and Jungle Slimes will be found nearer the surface, Hornets and Man Eaters at Underground Jungle depths, as well as Piranhas and Jungle Bats throughout.

Farming Underground Jungles
It is possible to find rare items such as Nature's Gifts and Jungle Roses in a player-made underground jungle. The seeds can be obtained by destroying tall jungle grass (the small pieces sticking out of the ground, not the mud block that has grass growing on it) which is found in the Underground Jungle.

The most efficient setup for creating an Underground Jungle "farm" for harvesting Jungle Spores and Jungle Seeds, in addition to Natures' Gifts and Jungle Roses, is to place a floor of jungle grass, and a ceiling 3 blocks in height. On the next layer up, do the same, but this time also add a middle layer so you have 3 lines with 1 space between each, and repeat. You can then harvest it easily by using a Muramasa, Blade of Grass, hammer or similar long reaching weapon or tool to harvest all 3 layers (the one you stand on and the two above it). Note that some items will get stuck above, but will be collected as you rise up the farm layers.

This method is sometimes questioned due to the vines that can hang down and prevent some items spawning. However, in Underground Jungle biomes, grass and roses seem to grow faster than vines, so this should result in better yields in a smaller space than a simple 3 block high tunnel farm. An additional row of Wood Platforms right under the ceiling will prevent vines from growing altogether, while also letting the players enter without increasing the height of the farm.
