Just read an article about growing pomegranates. I never thought about what they grew on. Sure sounded like a weed! Anyhow...it sounds easy to grow, but maybe not here in zone 6a. It would probably have to be potted up for me, but how do you keep a tree small while still bearing fruit of edible size?! Well if you live somewhere where you can grow them it's worth it, I think, since they cost about $2.50 each at the cheapest! Check it out:
Also, google for "pomegrante+plant" and you'll see what it looks like!
