The magnificent Sea Apple tree can grow up to 45 meters tall and have a trunk that is up to 75 cm in thickness. This versatile plant grows in sandy and rocky seashores, bamboo forests, savannahs, the edges of evergreen forests, and coastal forests. It is also often placed as a roadside tree in the interior. The Sea Apple tree stands out because of its straight stem and its rough, grayish buff or pinkish-colored bark with shallow cracks. The inside bark is just as beautiful, with shades of pale pink, dark brown, and pale yellow. It also has thin, straight twigs with smooth or slightly flaky bark that is brownish or grayish in color. The Sea Apple tree is a natural wonder and a beautiful addition to any garden.
The Sea Apple tree has leaves that are just as amazing. Each leaf has a petiole that is 1–1.5 cm long. They have a coriaceous texture and an ovate-elliptic shape. They are simple and opposite. The leaves are between 9.4 and 25 cm long and 4 to 13 cm wide. They have a pointy, curved tip and a whole edge. Each leaf has 16–20 side, parallel veins that run across the veins. These veins are easy to see and join into one vein that runs parallel to the leaf’s edge. The tops of the leaves are dark green and shiny, while the bottoms are light green. The leaf tips are turned down, which adds to their beauty. The leaves of the Sea Apple tree are pretty to look at, which makes it a great addition to any yard or landscape.
At the ends of the Sea Apple tree’s branches, there are beautiful inflorescences that bloom in terminal corymbose panicles or at the top of the leaf axils. These inflorescences are 10-15 cm long and have many hermaphroditic flowers. These flowers smell especially sweet and fill the air with their scent. They can be up to 3 cm across and have a white-yellow color. The calyx is 1.2 cm long and has four ovate lobes that are about 0.5 cm wide and overlap. The most noticeable part of the flower is the corolla, which has four oval petals that are 0.5 cm wide and a lot of white-cream stamens that are 1.2–1.5 cm long. The style of the flower is 1.2 cm long. Each flower has many stamens that are about 10 mm long and a style that is 9–15.4 mm long and longer than the stamens. Beautiful beetles and butterflies usually pollinate these flowers, which makes them a great addition to any yard or landscape.
After the Sea Apple tree’s fertile flowers bloom and die, they are replaced by juicy fruits that are round, elliptic, or oblong-elliptic berries that are 2–4 cm long and 1.3–3 cm wide. These fruits start out green and turn red as they get older. Each fruit has only one globose seed, which can be round or flattened and can be up to 2.5 cm in diameter. The birds, bats, and monkeys that help spread the seeds of the Sea Apple tree like to eat the fruit’s sweet and juicy meat. This complicated system of spreading makes sure that the Sea Apple tree can grow and live in many places around the world. This makes it an important part of many ecosystems.

Prevention and Control
Due to the different rules about (de)registering pesticides, you should look at your country’s national list of registered pesticides or contact the right body to find out which products can be used legally in your country. Pesticides should always be used in a way that is legal and in line with what the label says.
In Hawaii, the Galapagos Islands, and the Pitcairn Islands, where invasive Syzygium species are a problem, physical control methods like cutting down trees or frilling (removing all of the bark around the base of the tree stem) have been used along with herbicide applications. In a strong attempt to protect native plants, these steps have been taken. People have said that in Costa Rica, the invading Syzygium species, especially S. jambos, can be controlled by cutting down trees and replacing them with native species.
Syzygium species can be controlled with herbicides, and in places where they have become a major threat to native plants, both physical and chemical methods have been used to get rid of them. Syzygium cumini has become a big problem in Hawaii, the Cook Islands, and French Polynesia because it is grown so much as a fruit tree. It spreads quickly and makes a thick cover. So, chemical control methods are being used to try hard to get rid of this species. In the same way, Syzygium jambos is an invasive species on several Pacific islands, but herbicides have been used to limit it.
