Nether Warts are a type of fungus that grows in the Nether. It is typically found inside Nether Fortresses, it is used as a potion ingredient.

You have to find them in a nether stronghold. You can plant them in soulsand on the overworld once you have some from the nether.
They have to be planted in Soul Sand, from the Nether.
Minecraft 1.3+As long as Nether Warts are planted on soul sand, they can grow in any world.Pre-Minecraft 1.3 No. You can bring Soul Sand out of the Nether into the Overworld, and you can plant Nether Wart Seeds into it, but they will not grow. They will only grow if it is done in the Nether.
It looks like a small red ball and a stick on the bottom.
If you mined all of the nether wart in the nether fortress it ill not grow back on its own, however any left there will still be there. You will be able to find other sources of netherwart in the nether, possibly even in the same nether fortress.
