🍳

Grilled or Braised

Culinary

Unlike most lettuces, Little Gem's sturdy heads can be halved and grilled or braised, becoming sweeter and more caramelized while maintaining structural integrity. [source]

🍳

Caesar Salad

Culinary

Little Gem is particularly suited for Caesar salads due to its upright leaves and tender heart that hold dressing well. [source]

💊

Nutritional Support

Medicinal

Lettuce contains vitamins K, A, and folate, along with antioxidants and fiber that support digestive and immune health. [source]

Harvest Tips

Harvest when heads are firm and compact, typically 55-65 days after planting. Cut entire heads at soil level in early morning when they're crisp and full of moisture. For continuous harvest, cut outer leaves starting at 40-45 days. Harvest before temperatures exceed 75°F to prevent bolting and bitterness.

Fun Facts

🌱 Unlike full-sized romaine, Little Gem can mature in containers as small as 6-8 inches deep, making it ideal for small-space gardeners and container farming.
🌱 Little Gem's tender heart remains sweet and crisp even as outer leaves mature, making it one of the longest-harvesting lettuce varieties.
