A type of cabbage called Brussels Sprouts, imported from Australia, is being sold in Vietnamese supermarkets at a high price of 400,000 VND/kg due to its rarity and sophisticated transportation requirements. Each plant can yield 150-170 mini cabbages, weighing 50-60 cabbages/kg. The vegetable is popular for its nutritional benefits and is preferred by high-income individuals. Despite the high cost, consumers find the health benefits worth the investment.
