https://www.diggers.com.au/ have a variegated type. grow horseradish from cuttings or root tops.. buy a plant from farmers market or even supermarket if you can find it. Cut the top off and plant the top. It spreads quite easily if left alone. some nurseries and seed supply places have it but as its not very popular they don't list it on product pages. Suggest you contact them and ask.

Marina, I've been giving quit a lot of horseradish away over the past few months but the parent plant can still provide another one. What I do is pot the plant and allow it to stay there until it has settled and is producing new leaves then maybe another week or two which usually makes it fine for transporting, now it won't be full grown so whilst the root won't be suitable the leaves will. Would you like me to do that? Oh by the way I'm in Logan City. Roy

I kept the rootpieces in water through winter and spring in a cold glasshouse and they were rooting and making leaves. In Nov. or Dec. I planted them in a deep bucket and they are growing beautifully. I'll harvest after the first frost, if anybody wants pieces, pls contact me [email protected]. I'm in Elsburg, Germiston,Gauteng.

Hi Catherine, I use to mix the horseradish with beetroot and use it as a salad next to grilled steak or sausages. It is delicious! Ingredients: 3-4 small beetroots 1 small horseradish root Salt Splash of vinegar (optional – don’t use if using horseradish from a jar as it normally already contains vinegar) Mustard seeds (optional) Cumin seeds (optional) Method: 1. Rinse any mud off the beetroots and put them in a saucepan (metal is best; it might stain enamel) and cover them with water. 2. Bring the water to the boil and leave to boil for 30-40 minutes. 3. Drain the now very purple boiled water from the pan and refill with cold water and allow the beetroots to cool enough to be handled. 4. Clean off the skin (you should now be able to rub it off with your fingers, but use the flat of a knife to scrap it off if you like) and trim off any roots or stem stubs. (You can bake the beetroot and it will be more tasty and healthy) 5. Cut up the beetroots – you can grate it, julienne it, cube it, slice it...whatever you prefer. 6. In a separate bowl finely grate the horseradish. Be a bit careful here if you’ve never grated horseradish before as it’s tremendously powerful – I recommend you don’t hold your head over the bowl whilst grating it! 7. Teaspoon by teaspoon, add the horseradish to the beetroot and taste until you reach a combination you like. Don’t just throw it all in at once because if it’s too strong it’s hard to correct. Horseradish from the jar normally isn’t as powerful as fresh horseradish so you might need a few extra teaspoons. If you have any horseradish left over, put it in a small jar with some salt and vinegar and keep it for a dressing next time you prepare some beef or lamb. 8. Check the seasoning and add some salt and a splash of vinegar if you feel it needs it. 9. You can, at this point, add some mustard seeds (about a heaped teaspoon) or a sprinkle of cumin if you like these flavours. Mustard seeds aren’t so strong but be a little careful with the cumin as it can overpower. 10. Serve! Enjoy!
