Wax Jambu, Red (Syzygium samarangense)
Crisp, Juicy Bell-Shaped Fruit with Tropical Apple Vibes
Red Wax Jambu, also known as Java Apple, Water Apple, or Rose Apple, is a tropical fruit tree known for its glossy, bell-shaped fruit with a crunchy texture, subtle sweetness, and refreshing, watery bite. Native to Southeast Asia, this fast-growing evergreen is beloved for producing rosy red fruit that tastes like a mild apple crossed with watermelon and rose—especially cooling on hot summer days.
The tree itself is ornamental and lush, with glossy green foliage and pale pink to white blooms that attract bees, butterflies, and beneficial insects. It thrives in warm, humid climates, grows quickly, and can be pruned to maintain size—making it perfect for food forests, tropical orchards, and edible landscapes.
Wax Jambu is a prolific bearer that can fruit more than once a year in ideal conditions. It prefers full sun, regular water, and protection from frost. Whether you're growing it for fresh snacking, juicing, or just its striking appearance, Red Wax Jambu is an unforgettable tropical treasure.
Wax Jambu is in the Syzygium (Myrtle) family of plants, along with Jamun, Phak Mek, and Malay Apple.
