Re: The cold hardy list
Hi,
the balbisana is grown of seed. I don´t konw which form it is. I havn`t seen the balbisana in the botanical garden in Köln. But I know that this balbisana is there plant out for a few years. I get for a few weeks seeds of m.balbisana "new form".
The m.yangtse should be more harder (temperature) like a m.basjoo, but I havnt test it.
