Strawberry guava (Psidium littoralei) is also known as cattley guava, purple guava, or Chinese guava, although it is native to the Americas. Strawberry guava generally grows to heights between 6 and 14 feet (2-4.5 m.), although they can grow taller. As the name suggests, this tree usually produces red fruit, but yellow fruits are also possible.The fruit on the strawberry guava is similar to that of the common guava: a fragrant, juicy pulp with seeds. However, the flavor of this type of guava is said to have a strawberry essence and is considered to be less musky. It can be eaten fresh or used to make puree, juice, jam, or jelly.

Psidium cattleyanum, commonly known as Cattley guava or Strawberry guava, is a fruit-bearing tree in the Myrtaceae family. It is native to South America but has been introduced to various regions around the world, including parts of Asia, Africa, and Hawaii.

Cattley guava is a small to medium-sized tree with an evergreen foliage that is often grown for its edible fruit. The fruit is typically round or oval-shaped, similar in size to a small plum or cherry. When ripe, the skin of the fruit is thin and ranges in color from yellow to red. The flesh is usually soft and juicy, with a sweet and aromatic flavor. The taste is often described as a combination of strawberry and guava, hence the common name "Strawberry guava."

The fruit of Psidium cattleyanum is rich in vitamin C and other nutrients. It can be eaten fresh, used in various culinary preparations such as jams, jellies, desserts, and beverages, or even dried for later use. The tree also has ornamental value, with its attractive evergreen leaves and occasional white flowers.

However, it's worth noting that in some regions, Cattley guava is considered an invasive species, as it can spread quickly and outcompete native plants. Therefore, its cultivation and introduction into new areas should be done with caution to prevent potential ecological issues.

Overall, Psidium cattleyanum, or Cattley guava, is a fruit tree valued for its delicious fruit, which combines the flavors of strawberry and guava. It can be a tasty addition to tropical or subtropical gardens or orchards, but its potential invasiveness should be carefully considered in certain regions.
