Hass Avocado Over the years, the avocado has been called an alligator pear, custard apple, butter pear and vegetable pear. The name alligator pear originated from a the specimen that has a rough skin similar to the hide of our Everglades beast of the swamps. The Hass avocado is a variety of avocados with dark green, bumpy skin. It was first grown and sold by Southern California mail carrier and amateur horticulturist Rudolph Hass, who also gave it his name. Owing to its taste, size, shelf-life, high growing yield, and in some areas, year-round harvesting, the Hass cultivar is the most commercially popular avocado worldwide.
