Acerola is native to South America, southern Mexico, Puerto Rico, Dominican Republic, Brazil, and Central America, but is now also being grown as far north as Texas and in subtropical areas of Asia, such as India.It is known for being extremely rich in vitamin C, almost as much as camu camu, although it also contains vitamins A, B1, B2, and B3, as well as carotenoids and bioflavonoids, which provide important nutritive value and have antioxidant uses.

The Cistaceae are a small family of plants (rock-rose or rock rose family) known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom. This family consists of about 170(-200) species in nine genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in gardens.

The Annonaceae are a family, the custard apple family, of flowering plants consisting of trees, shrubs, or rarely lianas. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably Annona, Anonidium, Asimina, Rollinia, and Uvaria. Its type genus is Annona. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the other species Indomalayan.
