Mark, if you "haven't heard one good comment" about the taste of Wilma, perhaps you should re-read my post (Reply #17) in this same thread. Also, although I haven't experienced a truly cold winter since planting the Wilma & Opal, it got down to 27 this past winter with no appreciable damage (brand new flushes on the Wilma got crisped, but nothing else was harmed). A nursery owner about five miles from my house has three Mexicola Grandes growing in a service area with no protection from cold or heat, and they're doing fine. He says the fruit is delicious, but he rarely gets any because his workers steal them as soon as they're close to being mature. One of my neighbors had a couple of large (maybe 30 feet tall) Zutanos growing in his yard for many years. He eventually lost them to disease, but replaced them with another Zutano because he likes the fruit so much. The Westward Look resort a few miles from my house has a Mexicola and Zutano that are producing well, and the quality is high enough that they serve the fruit to their guests. It's just possible that what hasn't worked well in your area might might do better somewhere else. For example, in the late '30s and early '40s there was a 200-tree avocado grove of various types about a mile south of my home in Tucson. It was reported that the size and quality of the Duke avocados grown in Tucson was better than of Dukes grown in California. I, for one, applaud the efforts of Fygee and any other grower willing to expand our knowledge about how various avocados perform in challenging climates by actually giving them a try.
