The picture and the description are describing the plant cactus, not the item cactus. This is an item page and should either be treated as such or made from Cactus (item). -- ❤Kalilla❤ 23:23, 23 June 2011 (UTC)
It seems like the 'can't be in the ocean biome' requirement for growing cactus might be broader than that - the cactus farm I'm trying to build below my bamboo farm hasn't grown any cactus yet but has spawned a couple of very out-of-place looking jungle bushes. 107.77.204.155 15:49, 26 June 2020 (UTC)
