Seed Germination & Seedling
2-3 weeksSeeds germinate in 7-10 days at 60-70°F. Tiny cotyledons emerge followed by first true leaves. Seedlings are delicate and pale green.
Keep soil consistently moist. Provide 12-16 hours of bright light daily. Maintain cool temperatures (60-70°F). Thin seedlings to 2 inches apart if sown directly.
Vegetative Growth & Rosette Formation
3-4 weeksPlant develops 4-6 true leaves and forms a loose rosette. Leaves are elongated, tender, and pale green. Growth is bushy but still compact.
Maintain consistent moisture and cool conditions. Begin fertilizing with diluted balanced fertilizer every 2 weeks. Thin or transplant to final 6-inch spacing. Monitor for slugs and insects.
Head Formation & Heading Out
2-3 weeksLeaves begin to overlap and form a compact head. Inner leaves blanch naturally to pale yellow-green or cream. Head diameter reaches 4-6 inches.
Continue consistent watering; drought stress causes bolting. Maintain cool growing conditions (60-70°F ideally). Reduce nitrogen to encourage heading. Remove any yellowed outer leaves.
Mature Head & Pre-Harvest
1-2 weeks (window for optimal harvest)Firm, well-formed head with crisp inner leaves. Typically 6-8 inches tall with dense, overlapping leaves. Inner leaves are tender and sweet.
Monitor daily for signs of bolting (flower stalk emergence), which occurs quickly in heat (>75°F). Harvest in cool morning hours for peak crispness. Continue watering if not harvesting immediately.
Bolting & End of Season
Variable (days to weeks)If left unharvested in heat, flower stalk emerges from center. Leaves become bitter and tough. Plant rapidly goes to seed.
Harvest before bolting begins. Plant appears tall and opens up. If bolting occurs, harvest immediately or let go to seed for seed collection.

Harvest Tips
Harvest when heads are firm and 6-8 inches tall, typically 50-65 days from planting. Cut just above soil level in the early morning when leaves are crisp and full of moisture. Harvest before temperatures consistently exceed 75°F to avoid bolting and bitterness. Can harvest outer leaves individually while allowing head to continue growing for a second harvest. Heads typically last 1-2 weeks in refrigerator if stored in plastic bag.
Fun Facts
- 🌱 Little Gem was developed by Enza Zaden, a Dutch seed company, and introduced commercially in the 1960s-1970s as a response to demand for smaller, home-garden-friendly romaine lettuce varieties.
- 🌱 The name 'Little Gem' is a registered trademark for this specific hybrid cultivar; other companies sell similar compact romaine varieties under different names like 'Mini Romaine' or 'Sucrine.'
- 🌱 Lettuce is 95% water by weight, making it one of the most hydrating vegetables, and Little Gem's inner leaves naturally blanch to a pale color through reduced light exposure, mimicking commercial blanching techniques.
