The Hass Avocado Tree is one of the most widely cultivated and consumed avocados in the US. All Hass Avocado trees come from a single tree grown in California and named for the original owner of this remarkable fruit. The small, green fruit turns black when ripe, has a bumpy skin, small seed, and outstanding flavor.
Hass Avocado Trees have a long season, and are ready to pick from April through September. They are cold-sensitive below 32 degrees, and do best in full sun in USDA Zones 8 to 11. The Hass Avocado Tree can reach heights of 25 to 35 feet, and a width of up to 18 feet. They grow upright with small, dark green leaves and greyish-brown bark.
