The berries can be picked when ripe by right-clicking the plant. The bush itself can be obtained by breaking it like any other block (no special tool is required). They can be planted on grass or dirt. When planted, they are tiny, immature bushes which require some time to become full-sized.
Crafting Guide gives step-by-step instructions for making anything in Minecraft or its many mods. Just say what you'd like to make, what you already have, it will do the rest, giving you a list of raw materials and instructions of which items to make in the proper order. You can even ask it to include the materials and instructions for all the tools you'll need along the way!
Crafting Guide is free for all, but if you find it helpful, donations in any amount are gratefully accepted.
Crafting Guide is completely open-source, and you can help! Whether you want to write a recipe book (all simple JSON), or implement new features, just head over to GitHub to get started.
