Avocado Trees a Quick Introduction
Persea americana
By: Jason "Pepe"

Before finding it's way to Florida the evergreen avocado tree and it's fruit, had a long journey around the world.

The tree originates from Central America. The Aztec indians enjoyed avocado along with a wide range of other fruits and vegetables. The fruit has been cultivated for over 7,000 years. 

The avocado was introduced by the Spanish and Portuguese Conquistadors to the Antilles and the Caribbean circa the 1500's. Indonesia was next to meet and greet the avocado around the year 1750 and Florida began to see avocados in the mid 1800's.

The avocado is classified into three races. They are the Mexican, Guatemalan and the West Indian. Today many hybrid varieties exist between these races. The finest avocado trees are often hybrids with a rich history and also displaying superior charecteristics. Each avocado cultivar (Hybrid) has it's own name to reflect the uniqueness of the fruit. We are confident that today's avocado fruit would make an Aztec smile as he or she enjoyed dipping the tortillas into the bowl. How about you? Do you like avocadoes? Read more about the different types below.

Did you know this about the avocado? 
In Brazil they make avocado ice cream. Not sure about this one but hey what the heck, I would give it a try!

Tip: Avocado fruit will not ripen on the tree. Fruit does not fall to the ground when ripe. After being picked, a mature fruit will soften within three to seven days. So pick them as needed and enjoy. 


Powerful Nutrition: The avocado is high in monounsaturated fat (good fat) 
Benefits: Provides you with a rich source of energy and also antioxidants, folate and potassium.

Note:  Your Avocado tree will need to be planted in a well drained location and it needs plenty of sunshine!  Trees planted in areas that flood will kill the tree in 24 to 48 hours!

What's all the buzzzz? 
A & B flowers?
The avocado is unusual in several ways from other fruit trees. The timing of the male and female phases differs among varieties. There are two flowering types, referred to as "A" and "B" flower types. 

Bees will work closed flowers on Avocado trees!

Pepe's Says.....
"Don't worry about A or B flowers for backyard groves"
Here is one reason why! 
Source: California Master Gardeners Manual

Keep in mind that A and B type, means that male flowers and female flowers open on different days. 

Trees will often have some male and some female flowers open at the same time regardless of A and B type.


Commercial growers want cross pollination because it yields more fruit. You will still, for example, get fruit on a Simmonds without another tree of a different type (A or B) To complicate things even more, the temperature will also affect the number of male and female flowers open at one time. Bees often work Avocado trees very well. Bees will actually move the pollen out of the partially closed male flowers and deposit pollen on the female stigmas. Don't you just love those Bees?

This list shows the approximate season and the Avocado tree flower types. As an example, you can select one Oro Negro and one Lula Avocado tree. Both of these trees have a similar flowering season. Having one of each type will allow cross pollination and your trees will bear more fruit!
