This site tells you about it and you can buy it here.  It's not a plant as such, it's more of a ch emical reaction and you need to have the "plant" to make ginger beer, then you keep some from that to make your next one.

I used to make ginger beer when my children were growing up. If you knew someone who had a 'plant' they could give you some of thiers and away you went.

What you need is, about 2 teaspoons ofginger powder (the kind you use for baking) 2 of sugar and about 2oz yeast, and a small jar with a screw on lid - jam jar size is fine. Put all three into the jar and mix.

What you need to do then is to leave it to work for a few days and you're away!  To keep it going, you will need to 'feed it' with more sugar and ginger. Can't remember wether I used to add more yeast or not.

I made so much ginger beer from this that my kids got fed up with eventually!!

VERY IMPORTANT!! never screw the lid on tight as it will explode, I know from personal experience! I had to wash all the yellow mix  from my kitchen walls. The jar flew accross my kitchen and just missed me!!!

Alcoholic Ginger Beer

Equipment:-
• A jar and lid which is big enough to contain the plant
• One pint-sized measuring jug
• Several clean & dry two litre plastic bottles
• Teaspoons
• A large pan
• A fine cloth for straining
Ingredients:-
• Dried ginger
• Dried yeast
• Sugar
• Juice of four lemons
• Water
Making the Plant
1. In the jar place one teaspoon of dried yeast, two teaspoons of dried ginger, four teaspoons of sugar and a pint of cold water.
2. Stir and keep at room temperature.
3. Feed the plant every day with two teaspoons of dried ginger and four teaspoons of sugar. Stir after feeding
4. The plant will be ready in one week

Making the Ginger Beer
1. Place 1kg. (2lb) of sugar and two pints of boiling water in the large pan. The sugar will dissolve.
2. Add the juice of the four lemons.
3. Strain the contents of the jar through the cloth into the pan.
4. Add 14 pints of room temperature water.
5. Stir and bottle. Fill the bottles about seven eighths full as you need to allow for expansion. Squeeze the air out of the bottles to stop them exploding under pressure from the contents.
6. Store the bottles in a safe place at room temperature, and leave for three to four weeks to brew.
7. Discard half the solid from the plant or give it to someone so they may start their own. Place the remaining half in a clean jar with a pint of water and continue to feed as above.
