I had this in a pot kept under the edge of a tree where it got a little sun and a lot of shade, it did well and survived quite a harsh winter in 2009/10 with temperatures dipping as low as -11C at night. It seems to be able to withstand some frost, but not prolonged hard frost kept in a pot as the even harder winter 2010/11 with 7 weeks below freezing continuously with temperatures dropping as low as -17C killed it in the pot.

I had taken a piece of the plant and put it in the ground a couple of years ago, I put it in a dryish location which did not suit it so it barely grew. Our very dry year (in the UK) 2011 probably didn't suit it either but it did manage to regrow a little after the very cold winter! The secret seems to be winter dry, summer wet, with some shade and plenty of organic compost which is what I grew it in in the pot and added to the ground where I planted it although the soil there is very poor and sandy. If it grows again next year I will certainly be trying to grow it well again in a pot, and maybe bring some inside over winter as it is well worth the effort.
