These evergreen fruit trees have been cultivated in different geographical regions for millenia, which has given rise to three distinct “races” of avocado: Guatemalan, Mexican, and West Indian, aka var.

There actually can be a bit of variation to the fruits: the form can be round to pear-shaped, the skin can be smooth to coarse, and the color can range from green to dark purple. You’ll need to plant Type A and Type B varieties near each other to make this happen… but in a pinch, self-pollination is also possible for some varieties.Īfter insect-mediated pollination, the flowers give way to the famous fruits, which are botanically considered berries – fun fact! This behavior, known as “protogynous dichogamy,” encourages the cross-pollination and genetic diversity that leads to more robust organisms. Avocado varieties with Type A flowers open their female bits in the morning of Day One and their male parts in Day Two’s afternoon, while those with Type B flowers open their female parts in the afternoon of Day One and their male parts in the morning of Day Two.Įach opening only lasts for about half a day.
