770:, Hass planted three seeds he had bought from Rideout, which yielded one strong seedling. After trying and failing at least twice to graft the seedling with branches from Fuerte avocado trees (the leading commercial cultivar at the time), Hass thought of cutting it down but a professional grafter named Caulkins told him the young tree was sound and strong, so he let it be. When the tree began bearing odd, bumpy fruit, his children liked the taste. As the tree's yields grew bigger, Hass easily sold what his family did not eat to co-workers at the post office.

The wood was stored in a tree nursery and from this stock, a nephew of Rudolph Hass, Dick Stewart, made keepsakes, jewelry and other gifts. From 2010 to 2013, in mid-May, and starting again in September 2018, the city of La Habra Heights celebrated the Hass avocado at its Annual La Habra Heights Avocado Festival.

California Hass Avocado groves have good soil and drainage, plentiful sunlight and cool gentle winds from the oceans which help the fruit grow. These conditions hold throughout the year, so there are always fresh harvests of Hass avocados in Southern California.

Hass avocado trees, like some other cultivars, may only bear well every other year. After a year with low yield, often because of cold, for which the tree does not have much tolerance, yields may be very high the next year. However, the heavy crop can deplete stored carbohydrates, lowering the
