Hi everyone,
I realize this is a very old post, but there seems to be quite a bit of interest in olive tree growing in North Carolina. I have been researching and trying different varieties of olive trees here in Mocksville, NC, Zone 7b. So far I have had success with the Vassilika variety, now about 6’. This past winter (2024-2025) was cold enough and dry enough to have killed back an established Magnolia figo, Banana shrub on the north side of my house. This has never happened before. But my Vassilika olive on the east side of my home out in the lawn with no wind protection has survived the last 3 winters with little to no damage. I also have Nitkitshyana that died to the ground in the winter of 2022-2023, but has since grown to about 6 feet high and wasn’t affected by last winter. I have 2 Arbequina olive trees in the garden. The first one is out in the yard, fully exposed. It died to the ground this past winter and has since grown back to about 2’ tall. The second one is on the south side of my home about 10’ from the house and has some wind protection. It is in a half whiskey barrel and I put mulch around the exterior of the barrel over winter. It has been outside now for 3 winters and has had no damage. I hope my experiments might help others of you interested in olive trees.
There is also a 20+ year old Arbequina olive tree growing at Plant Delights Nursery in Raleigh. Tony Avent, owner, says it has never been damaged by cold. I saw it the last time I was there and it is about 12-15’ tall and about as wide.
