I wondered if anyone has given this a go. I got a plant from the garden centre today, and checked it out on Google, but it's nice to hear about other people's experiences. It looks a bit like a tradescantia, and there are a few roots at some of the leaf joints, so I've already taken one cutting. I chewed a leaf, and it's a bit like ordinary coriander, but I need to get a few more plants going before using too much. I'm keeping it on the kitchen windowsill as it needs heat this time of year.
