Ximenia americana (Hog Plum, Sea Lemon) is a member of the Myrtaceae family. This plant has a widespread distribution, ranging throught the subtropics and tropics of the world. It is found in Florida, Central and South America, throughout most of Central Africa, India, Australia, and islands in South east Asia(Kew). It’s pretty interesting to see a large seeded species have a circumtropical/subtropical distribution. This species seems like it has a lot of potential in somewhat colder climates and may present possibilities for growers in climate zone 9b and up.
