Iris, horse radish is a completely different plant. It would be unusual if you had some seeds as they are usually grown from cuttings. What you might have is a daikon radish. They grow a long white root.

If it is celcius, then yes, otherwise, "Best planted at soil temperatures between 50°F and 77°F."

I too have been looking for horseradish. Isabel Sheppard sold me some when we lived on the Sunshine Coast but it died and anyway, you cannot bring plants to Tas.

Head to Chung Sing's vegetable wholesaler in Campbell St and you can buy some if in stock otherwise they can ring the supplier and order some in. Transplant that.
