I once bought white radish (daikon) at a market and was told it was parsnip! radishes and horseradish are totally different plants. Radish is grown from seed and the root is harvested when it is ready. Horseradish can be grown from seed but is normally grown from root pieces. It is 'very friendly' and will spread whereas ordinary radishes will only grow from seed. Trust this helps

tasting store bought horseradish and reflecting how mild it is, how is it that (imitation) wasabi which is also made up of horseradish is so pungent.

Store bought horseradish cream contains less than 10% horseradish (this may vary) and contains vegetable oil, milk, etc which would tone down the bite. As real wasabi is expensive a lot of wasabi paste is boosted with mustard seed flour. This may also help explain the variation.

I live in Darwin and would like to try and grow horseradish here. Hearing it likes frosts is it worth a try?

The best store bought horseradish I found was in the refrigerator section of The Kosher Providor, Plantation Street, Menora.

Try Bunnings herb section, I bought a plant just yesterday there, but they only had a few plants--I can speak for other stores other than my local one, but as I said, they only had a few plants. The tag had 'food for life' on it-I'm presuming that's the company that is distributing them at the moment. Because there were only a few plants, it was hard to find- Good luck!

I would try local growers markets, traditional green grocers or organic gardening groups. You will find these on the internet or markets are often listed in local papers.
