Persea americana also known as the avocado tree, is a large dark green evergreen tree with a low-branching open canopy. It is often grown for the production of pear-shaped avocado fruits, which are edible to humans, and found in most grocery stores around the world. Each tree produces between 100 - 500 fruits per year. There are several different species of avocado trees which can be tall and upright or low and spreading. They blossom small greenish-yellow flowers that grow where the leaves join the branch.
All parts of P. americana, including the fruit, are toxic to poultry. The fruits and tree contain up to 69% oleic-acid, palmitic-acid, and persenone.
