Oman’s Hidden Summer Gem: The Season of Al Zam Fruit

By Mohamed Al Battashi

As Oman enters Qayth season (date harvest season when temperatures begin to swelter), attention often turns to the country’s famous summer produce. Yet among the mangoes and ripening dates, another seasonal gem quietly emerges from mountain valleys and family farms: Al Zam.
Known internationally as jambolan or Java plum, Al Zam is one of Oman’s lesser-known summer fruits. Oval-shaped and deep purple when fully ripe, the fruit has a juicy flesh with a sweet flavour and a slight astringent note. For many Omanis, however, its appeal goes far beyond taste.
Environmental activist and Green Branch Award recipient Mohammed bin Saeed al Hinai describes it simply as “the fruit of summer in Oman.”

The harvest season typically begins in May and June and continues through July, occasionally extending into August depending on weather conditions and water availability. The trees are commonly found in mountain valleys and wadis, particularly in areas such as Wadi Bani Kharous in Al Awabi and Wadi Al Saq in Al Hamra, where they thrive in the local environment.
For Yahya al Battashi, whose farm has been home to many Al Zam trees for more than 30 years long, the arrival of the season is an annual family event.
“The fruiting season is something we look forward to every year,” he says. “The fruits begin green, then gradually turn pink or light purple before reaching their final dark purple, almost black colour when fully ripe.”
According to al Battashi, the best time to harvest the fruit is when it becomes dark and separates easily from the branches, signalling peak flavour and quality.

Despite being planted more than three decades ago, his tree continues to produce generous harvests each year. Beyond its fruit, the tree provides broad shade and remains a valued feature of the farm.
For many people, Al Zam is closely linked to childhood memories. Generations grew up picking the fruits directly from the branches during summer holidays. One of its most recognisable traits is the purple stain it leaves on the tongue and lips, a familiar sight among anyone who has enjoyed the fruit fresh from the tree.
Interestingly, the tree’s adaptability extends beyond Oman. Saudi environmental consultant and wildlife volunteer Obaid al Ouni notes that Al Zam has been successfully cultivated in Riyadh despite the city’s harsh direct sunlight, even though the species is generally associated with more humid environments.

Today, the fruit is becoming increasingly visible in local markets and fruit shops. Khairat Mazareana recently announced the availability of large quantities of Omani Al Zam, with 600-gram boxes selling for RO 2.400.
As interest grows in local produce and agricultural heritage, Al Zam serves as a reminder that some of Oman’s most remarkable seasonal treasures remain hidden in plain sight. More than just a fruit, it represents a connection to nature, family traditions and the agricultural rhythms that have shaped Omani life for generations.
