Latin name: Eutrema japonicum
Location: Japanese Edible Garden (though it is a perennial so you won’t see it in winter)
What it looks like: The Wasabi plant, otherwise known as the Japanese Horseradish, has heart shaped mid-green leaves each sat on top of its own leggy light green stalk which all meet in a clump at the base. 
History: Wild Wasabi is native to Japan and has been eaten there since 14000BC! Wasabi has only been farmed in England since around 2010.
How to eat it: Wasabi roots are ground up to make a condiment to other foods, most commonly sushi dishes. The paste should be eaten within 15 minutes of preparation to avoid losing the flavour.
More information: The Wasabi plant comes from the same family as horseradish, mustard, cauliflower and broccoli!
