Description
A quintessential Romaine lettuce, Parris Island Cos has earned its place in Australian gardens through its adaptability, crisp texture, and dual-purpose harvest potential. Renowned for its upright growth habit, this variety forms tall, sturdy heads up to 30 cm, adorned with strong, deeply veined leaves and a signature white midrib that delivers a refreshing crunch.
Whether harvested young for tender baby greens or allowed to mature into full, statuesque heads, this heat-tolerant lettuce thrives in Australia’s variable climates, offering flexibility for gardeners from the tropical north to the temperate south.
Culinary versatility is a hallmark of Parris Island Cos. Its mildly sweet, mineral-rich leaves are a nutrient-dense addition to meals, packed with vitamins A, C, and K. While traditionally grown to full size, its rising popularity as a baby leaf reflects modern culinary trends, offering chefs and home cooks alike a tender yet crisp texture for mixed greens or gourmet garnishes.
