I do not like horseradish, but I am a seed and plant maniac.Yesterday (Sunday 18th May 2014) I found dryish pieces -roots- at our local PnP in Lambton, Germiston. I will re-hydrate them to hopefully revive them and see if they will grow. Will keep you posted.

Have you found your horseradish yet? I can let you have a few plants if you're still looking, I don't have many, but it should do for your own use.

Ferndale Nursery in Constantia, Cape Town has plenty horseradish plants for sale. Owner Errol has been growing it for many moons. Around R32 for a nice size plant.

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
