I saw this 'Giant Citron' for sale on this website. A google search found nothing about this variety of citron. Does anyone grow this variety or have more information on it? From the photos it certainly does look gigantic, to my eye it looks bigger than the pomelo they sell, but it's hard to judge.

This is a variety propagated by the Tintori nursery.

Thank you very much Mike, your info and website are excellent. I'm tempted to buy one of these giant citrons now lol. 3kg fruit, amazing. I would love to visit the Tintori nursery one day.
