We are in hot country here collo and my dad had a plot of them along the driveway fence. 8 foot tall plants with sunflower like flowers (but much smaller), came up evey year.
I grew up eating roast artichokes with the roast potatoes, carrots, parsnips etc, every sunday.
Two hours later you could fart out the candles on grandmas birthday cake LOL
Add some roast onions to the meal and you could gas a stadium
