It's a tender perennial. Have a look at the website above for care. BTW, it's poisonous, but you weren't going to eat it, were you?

thanks beattie no wasn't going to eat it, a friend brought it from germany as a root in a packet as the instructions were german i just threw them away. thanks again beattie.
