The Lamb Hass avocado is a high-yielding, late-season, pear-shaped variety (10–18 oz) developed from a Gwen and Hass cross. Known for its thick, black, pebbly skin and rich, creamy yellow flesh, it is popular for its high yield, easy peeling, and late harvest (May–December). The tree is a compact, upright, and self-fertile Type A, ideal for small spaces and home gardens.
Key Characteristics of Lamb Hass
  • Fruit Quality: Similar to Hass, with rich, creamy flavor and a relatively small seed, offering more flesh, according to Greg Alder’s Yard Posts and this YouTube video. The skin is thicker than Hass, notes Greg Alder’s Yard Posts.
  • Harvest Season: Late-season, ripening from May/July through December, allowing for a longer harvest compared to traditional Hass, notes Four Winds Growers and Quieronaranjas.
  • Tree Habits: Compact and upright, usually growing 15–25 feet tall, as detailed by Four Winds Growers and Fast Growing Trees.
  • Hardiness: More salt-resistant than typical Hass, notes this YouTube video.
  • Pollination: Type A flower, self-fertile but benefits from companions like Sir Prize or Bacon.
Lamb Hass was developed by the University of California and released in 1996, bearing the name of Bob Lamb, who ranched in Camarillo, California, according to gregalder.com.
