Wow... i grew 2 kinds last year and only 1 made it through the winter its leaves are more silverery.
I'll take a picture soon (transfering pics to here is a pain at the moment so i tend to do loads at the same time)
I don't get flowers though, just hoping if i can get the size to it i can grow it outside one day.
I keep trying these plants that shoudn't survive here! Hey its part of the fun though.
