I will say dont bother to grow from seeds, buy the all plants and every 2 or 3 years take some cuttings and grow new plants from it...after a couples of years, plants tend to loose their scent and flavor, so to grow new ones...its a very hardy plant if on a nice warm spot, with a soil even poor and with easy drainage, some say the more harsh condition, the stronger the flavor...well maybe me, my Mediterranean gran' perhaps...
