Artichokes and their hearts, its like they were just meant for bad jokes.
But really, if they grow well in your climate, you just have to keep them growing. You don't have to plant them again and again every year.
As long as the weather doesn't kill them, almost nothing else will.
Really easy farming.
Bon Appetite.
True, they are perennials so they can keep producing. In some places, it gets too hot for them, though.
