Horticulturist Rudolph Hass (a Southern California mail carrier) was the first to grow the Hass cultivar, and that is where it got its name.
The Hass cultivar is the most harvested commercially popular avocado worldwide. 80% in the United States, 95% of California crop, and is the most widely grown avocado in New Zealand.
The Hass avocado is a large-sized fruit and has dark green-colored bumpy skin. When ripe, the skin turns dark purplish-black and yields to gentle pressure. When perfectly ripened, the inside becomes white-green in the middle part of the inner fruit.
Of course, adding healthy fruits to your daily diet is wise. However, eating organic fruits is smarter. Why? No chemicals. Eating foods with minimal chemicals helps prevent early illness.
All commercial, fruit-bearing Hass avocado trees have been grown from grafted seedlings propagated from a single tree developed from a seed bought by Rudolph Hass in 1926 from A. R. Rideout of Whittier, California.
