Most people around here in SE Texas seem to grow meyer or ponderosa. I thought I'd be a little different. I know nothing about the Iranian. It looks related to citron by the leaves and large size. I'll get to see what all the fuss is about yuzu this year. GalGal is from India and is like a large meyer. I've propagated lots of lisbon. I figure if someone is growing ponderosa which is not very cold hardy, the least they could do is grow a good tasting lisbon, the grocery store lemon.
