In 2002, the tree to which every Hass Avocado in the world can trace its lineage finally succumbed to root rot at the ripe old age of 76. Her offspring account for 95 percent of the avocados grown in California, and the fruit of her labor resulted in one of the state's most important industries. Yet, despite speculation to the contrary, nobody knows what variety of seed produced the original Hass Mother Tree. The tree began life as lucky-find; a simple seed planted by A.R. Rideout of Whittier. Rideout, an innovator and pioneer in avocados, was always searching for new varieties and tended to plant whatever seeds he could find, often along streets or in neighbors' yards. In the late 1920s, Mr. Rudolph Hass, a postman, purchased a seed from Rideout, and planted it in his new orchard. He planned to graft another variety on it, but when repeated grafts didn't take he planned to cut the tree down. Fortunately for avocado lovers everywhere, Hass's children talked him out of it.
