Olive trees are very cold hardy (14 degrees), evergreen, self-pollinating, wind & drought tolerant, do not get attacked by insects or diseases and best of all will give you black olives to pickel.
We have been growing them in Howey for 8 years now and our sizes range from $15 to $195 (1 foot tall to 9 feet tall). Here is a photo displaying 4 of the 6 sizes we currently grow and sell.
