The guava plant, scientifically known as Psidium guajava, is a small evergreen tree or shrub typically reaching heights of 10-20 feet. It boasts a dense canopy of glossy green, oval-shaped leaves with prominent veins. The tree is known for its white, fragrant flowers and its characteristic fruit, the guava, which can vary in shape (round or pear-shaped) and color (green to yellow when ripe). The flesh inside is usually white or pink, juicy, and contains many tiny edible seeds.
