The Fantastic Avocado Tree is considered one of the most cold-hardy avocado trees, with some trees known to survive brief periods of temperatures as low as 10 degrees F. Other individual trees have sustained little to no damage at temperatures as low as 15 degrees. However, all avocado trees do best in climates that do not receive long periods of freezing weather. Fantastic Avocado Trees can be grown in the ground in USDA Zones 8 to 11. Fantastic Avocados are a medium to large fruit, growing to about seven or eight ounces. The fruit is dark green, bumpy, and has very thin skin. Once cut, the large seed releases easily from mature fruit. The flesh is smooth and has an agreeable, nutty taste that is of high quality.
