A white guava tree (Psidium guajava) is a tropical fruit tree known for its sweet, aromatic, white-fleshed fruit with a pear-strawberry flavor, offering high Vitamin C and antioxidants; it's a relatively easy-to-grow, ornamental, and productive tree for warm climates (Zones 9-11), needing full sun, well-drained soil, and regular water, producing fruit that's great fresh or in jams.
