Many navel varieties produce their fruit in late fall or early winter. However, as your in Ontario your fruiting season could be earlier or later.

OHHHH WOOOW that is a huge amount oh well i guess i will never know.

Look on the tag that came with the tree. If it shows the name of the propagating nursery, you can telephone them, tell them where you purchased the tree, and ask them which variety of navel it is. They should be able to tell you that information. - MIllet

Well on the tag it said grown in Canada at Colasanti's Tropical Gardens where is where i bought it so i am guessing that they must of bought budwood from somewhere and grown their own stock and grafted varieties onto the stock.

The most common "Early" navels are Washington & Cara Cara (Red Navel). There is also a Dream navel that is a early variety.

I think I may have something to offer Millet:
Marrs early navel
Variegated cara-cara navel

Oftentimes even credible nursery retail stores interchanged navel with valencia names such as Rohde Red. Also I have seen labels such as Fremont Navel, Kishu Navel, Kara Navel, etc, even though these are mandarins. I won't be surprised if I come acoss names like Kishu Tangerine, Kara Satsuma...

I find that at the grocery store they change up names too, today i found a tangelo being sold as orange. I am also excited because i found pommelo today can't wait to try it.
