Avocado (Persea Americana)
Now imagine a stately tree that is not only a provider of shade but also a source of the superfruit known worldwide for its rich, buttery flavor—the Avocado. Officially named Persea americana, but more affectionately known as the avocado tree, this lush, evergreen giant is a staple in gardens where the climate smiles warmly all year round. Originating from the highlands of south-central Mexico, the avocado tree is a symbol of growth and health, flourishing under the sun to bring forth fruits that are as nutritious as they are delicious.
From its broad, vibrant green leaves to the clusters of subtle, greenish-yellow flowers that promise fruits, the avocado tree is a sight to behold in any landscape. Each season, the flowers mature into the plump, green-skinned avocados that dangle enticingly from the branches, almost like nature's own ornaments. The allure of growing your own avocados extends beyond the pleasure of harvesting them; it's about watching these magnificent trees turn sunlight into the creamy, delectable fruits that enrich our meals and nourish our bodies. In the life of an avocado tree, every bloom and every fruit tells a story of natural abundance and culinary delight, making it a cherished addition to any gardener's green space.
One of our valued pet business clients recently relocated out of state and entrusted us with the avocados she had lovingly grown from seed. As avocados do not grow true to seed, these saplings will develop into entirely unique varieties. We are excited about the possibility of discovering a delicious new avocado among them. Should one of these new varieties prove exceptional, we are considering naming it "Ocal FF." It's always rewarding to embrace experimentation in our new food forest.
Any reference to medicinal or culinary use of plants or plant parts should in no way be considered an endorsement by The Ocala Food Forest or its staff. Research is crucial in safe and proper consumption or experimentational use of any plant.
