Hass avocado is a cultivar of avocado, and it has a cute history. In 1925, Mr. Rudolph Hass, an amateur horticulturist, bought a small 1.5 acre avocado grove in La Habra Heights, Southern California. His plan was to graft old Fuerte avocado branches – at the time, Fuerte was the best avocado cultivar – with young saplings grown from some avocado seeds, which were sold at a local nursery. Those seeds were cross-pollinated many times by nature, and the grafting did not go well for one of the young trees [little stubborn sapling!], but per his grafter’s advice, Mr. Hass kept that sapling to see what would happen anyway. When the sapling was only over a foot tall (some time in 1926), it bore three fruits [d’awww!].
Normally, the Fuerte cultivar would take at least five years to produce fruits. Not only the odd stubborn young tree grew faster than the Fuerte, it also grew straight up and did not spread as wide, so it was more land-efficient (more trees per acre). Most importantly, its fruits tasted the same, if not better than the Fuerte. Hence, the Hass avocado became the most popular varietal, making up 95% of all today commercially grown avocados. [Moral of the story: don’t cut down your tree even if it refuses to do what you want at first. 🙂 ]
