After a trip to Poland in 2007 and 2009 I've grown to love horseradish. You can't buy it strong enough here so I want to grow my own or hope to buy some. I live in Sydney, Ryde area. Dziękuje

Ted, with all these people wanting horseradish plants,you should consider filling this need with your 'out of control' supply. Plants will grow from apiece of root, so it shouldn't be difficult to send thru the post.Root cuttings are planted in early autumn.

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.
