Thanks Sheila! I'll be back there in the spring to pick up a few things to try planting. The first visit, I was with someone else who was actually shopping. I didn't need anything, so I was free to roam. I don't think I've ever enjoyed going to the store as much! The clerks were helpful and I had time to really look at everything.
I thought about jicama, but it grows on a vine from seed. The seeds are in a pod on the vine after the jicamas have been harvested. They're supposed to be poisonous, but when planted, produce the vine the jicamas grow on. It wasn't a vegetable I could pick up, take home, and plant like the others in the article.
