I have grown it reasonably successfully here - it needs a lot of water!!

I make a compost tea out of it and manage to get two harvests a year. It is dying back now and I will be transplanting it in the spring.


I originally grew it from seed (from the UK) and it takes a fair while to germinate, but gets there in the end. I also sowed some self-seeding from the USA, but whilst it has come up quite nicely, there is no evidence that it is producing fertile seeds.
