Citrus, Glen Navel Orange 'Glen'

From justfruitsandexotics.com:

"'The Glen navel orange tree originating from Glen St. Mary’s Nursery in North Florida. ...Read MoreA mutation of the popular Washington navel, the Glen navel orange tree unlike Washington navel orange tree perform more reliably and have better quality fruit in the hot humid climate of Florida. Glen navel orange is one of the foremost navels relied upon for commercial production here in Florida. Bountiful crops of large, bright orange fruit with an open, non-protruding navel. Super sweet, excellent flavor. Fruit ripens early November to January. Self fertile."

When I bought this tree, it was advertised as being hardy to zone 8a with protection. In reality, it is probably only hardy to the low 20's before it gets real damage.

I live in zone 8b, where it's first winter had a low of 17 degrees: it was covered only with a loose blanket which blew off during the night. It defoliated and much of the outer branches were lost. But during the next growing season, it flushed out with growth and continued right on.

I try to cover mine with blankets and place a spotlight under when the temp looks like it will get below 26-27 deg F. Although, more than once, I failed to cover it when it has gotten in the low 20's. During the January 2014 Gulf Coast Ice Storm it was not covered: everything was coated in freezing rain, the temp dropped to 20 deg that night, and it didn't get out of the 20's the entire next day. Despite this, damage was minimal! It is located on the west side between two houses. Glen navel orange proves to be a fairly hardy and resilient citrus. After the aforementioned ice storm, it profusely flowered for the first time, and I was rewarded with it's first crop of navel oranges. I think I could say they were the best tasting orange I've ever had, and juicy too!

This is a great navel orange variety that is well adapted to Florida conditions. I added a picture above of my mentioned tree.
