Hass Avocado (Persea americana) 

Hass avocado is the most popular variety here in US.  It is well known for its creamy delicious taste. The fruit is small to medium size compare to other variety. It has green bumpy skin which turns into dark purplish color during its peak ripeness.

The avocado is a dense, evergreen tree, shedding many leaves in early spring. It is fast growing and can with age reach 80 feet, although usually less, and generally branches to form a broad tree. Some cultivars are columnar, others selected for nearly prostrate form. One cultivar makes a good espalier. Growth is in frequent flushes during warm weather in southern regions with only one long flush per year in cooler areas. Injury to branches causes a secretion of dulcitol, a white, powdery sugar, at scars. Roots are coarse and greedy and will raise pavement with age. 

These are grafted plant. They are between 2-3 feet in height.
