Red-fleshed jackfruit, a rare variety, is being sold in Vietnam at prices 5-6 times higher than regular Thai jackfruit, with some retailers charging up to 180,000 VND per kilogram. The high price is due to the variety's rarity and high production costs, as it requires specialized cultivation and is more difficult to grow than the common variety. Originating in Malaysia and Indonesia, the red-fleshed jackfruit is becoming more popular in Vietnam, despite its high cost and limited availability.
