Yellow guava is a small tree up to 10 m in height. It has spreading branches, and characteristic copper coloured bark which flakes away to reveal the pale green layer beneath. The wide green leaves are oblong in shape, leathery, aromatic when crushed and downy on the underside. Leaf dimensions are 7?15 cm long and 3?5 cm wide. The flowers are creamy white, and shed their petals to leave a tuft of yellow tipped stamens. The rounded fruits have yellow skins when ripe, with pinkish red flesh, and can be between 5?10 cm in length.
