It's a real treat to serve up your own brussels sprouts on Christmas Day. Igor is ready to harvest in November/December, so the timing couldn't be better. What's more it's an incredibly vigourous F1 variety and produces dozens of tight mid-green sprouts per plant.
That said, the plants will take up a lot of ground, for a long period of time. If space/time is tight and you want higher yield greens opt for kale or swiss chard.
