This is a standard green globe variety, grow as a perennial will grow as annual in northern climates everyone loves artichokes but not a lot of people know how to grow them. They very hard to get. A harvest in the first year. But with A little tlc. It can be done the trick is start your seeds early. And put them out. Then let the frost hit them and bring them back in. And then plant them. This tricks them into thinking they went through a winter. Happy growing!!!!
