This addon adds 9 variants of trees that drop minerals, each sapling can be crafted and works like a normal sapling. The trees added are cobblestone, coal, iron, gold, redstone, lapis, diamond, emerald, and quartz.
To obtain the saplings you need to craft 1 sapling of a lower tier and 8 ingots of the tier you want to craft. So to make a cobblestone sapling you need 8 cobblestone and 1 sapling and to make a diamond sapling you need 8 diamonds and 1 lapis sapling.
It takes 2-6 minutes for a tree to grow and 20-60 seconds for the leaves to decay. The leaves have a 10% chance to drop saplings and the logs have a chance to drop ores and will always drop an oak log.
