Are places unusually hot in summer, such as Phoenix, AZ area, too hot for horseradish to grow, assuming it's being watered throughout the summer months?

It's not too hot, but in place like Nul Arbor plain in Aus., better to plant in Winter, & be sure to water.

I bought white radish at thane market and was told that is also horse radishould is it true?

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.
10 May 17, Ken (Australia - temperate climate)
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.
