Better Cacti: makes it possible to create semi-realistic Saguaro cacti using the debug stick to cycle through age states. They will not grow in these shapes, as the cacti generally only use ages 0, 1 and 15. (Also includes an optifine only feature that changes sweet berry bushes in the badlands and desert biome variants into prickly pear cacti.)
Better Water Plants: adds bulrushes using the unused blockstates for the mangrove propagule.
Better Bamboo: adds better bamboo colors and two variants of both bamboo sizes, a green and a golden variant.
