It is a tender perennial in this country but is easily raised from seed each year-if you want to take cuttings and over-winter them you will need to protect them-do it around August/September time
As a new gardener I found this article just the thing I needed. Many sites and magazines seem to be for established gardeners and sometimes don't give the basic info. How often do you water? from the bottom or the top? I planted some seeds this year which came up and then died off again. Quite disheartening really but I'll keep trying.
