Yes, I have grown one. This year will be the first year that I get a harvest from it. There was another person that posted in the Texas gardening forum a while back about growing artichokes in Dallas which might be helpful.

I planted a green globe artichoke from a purchased seedling last year. In the middle of summer it did have a hard time with the heat, but recovered each evening. I have had some aphid problems and caterpillars, which I sprayed with a bit of neem or manually evicted.

It's been a trooper, my son pulled the whole plant up about one month after I planted it. Eventually it bounced back from the dead and grew about 4' diameter of foliage before dying back from winter frosts.

I don't give it any special treatment really. It is well mulched (3-4") like everything in my garden. I amended the soil with compost (3") beneath the mulch that I turned into the soil a little with a garden claw. Then put a little bit of soybean meal on top for fertilizer.

I am anxious about what I will see this year from it. Should be a beautiful (and delicious) plant.

Hope this helps.
