Solved ID this lovely thing please

hallo All.,

probably obvious to everyone nut myself--- bought last year, successfully mollycuddled over -20 winter and it is now repaying my care and attention --- this lovely thing is set to go on for a while longer but until i know what it is i dont know what sort of soil it needs, how to feed it, etc.

thanks for your help. karaman

thanks, apreciated - cant work out how to do an image search - the instructions i've had are about as useful as a wet sponge in the arctic -- karaman
