Minecraft wiki entry for Beginner%27s_guide, associated text: Along the way, keep an eye out for useful plants. Keep breaking grass for seeds as you pass it, and grab a few of other plant types that you encounter, except perhaps for flowers. Flowers are not very useful yet (though dandelions might be helpful for catching rabbits), but more useful finds (depending on where you are) include pumpkin blocks, sugar cane, melons, cactus, and sweet berry bushes. If you find any of these, break some of them and take the results with you for later farming. Be careful with cactus and berry bushes, as they harm you if you touch them! "Using" a berry bush can drop the berries without breaking the bush, but the bushes are common (not to mention hazardous), and if you do want more bushes, you can just plant the berries.
