Meet Little Gem Lettuce
A compact miniature romaine forming tight, sweet heads about six inches tall, perfect for individual serving-sized salads. Combines the crunch of romaine with a sweeter, more buttery flavor in a space-efficient package. Excellent for container gardening and close-spaced intensive beds. More bolt-resistant than standard romaine, extending the harvest season into warmer weather.
When to plant Little Gem Lettuce
Sow seeds one-eighth inch deep in moist seed-starting mix at 60 to 68 degrees Fahrenheit. Do not cover heavily as lettuce needs light for germination. Germination takes 5 to 8 days. Grow seedlings at cool temperatures of 55 to 65 degrees under bright light. Transplant with 4 true leaves after 5 to 7 days of hardening off. Direct sowing in garden beds also works well from spring through fall.

How to grow Little Gem Lettuce
Little Gem is a miniature romaine-butterhead cross producing compact, sweet, crunchy heads about 6 inches tall. Start seeds indoors 4 to 6 weeks before the last frost or direct sow in early spring. Sow seeds one-eighth inch deep, barely covering them as lettuce needs light for germination. Space plants 6 to 8 inches apart in rows 10 inches apart.
Little Gem thrives in cool weather between 55 and 70 degrees Fahrenheit. It is more heat-tolerant than many lettuces but will bolt when temperatures consistently exceed 80 degrees. Succession sow every 2 weeks from early spring through fall for continuous harvest.
Keep soil consistently moist with light, frequent watering. Mulch around plants to keep roots cool and retain moisture. Little Gem matures quickly in 50 to 60 days, making it ideal for intensive gardening. Its compact size makes it perfect for containers, raised beds, and small spaces. Apply dilute liquid fertilizer every 2 weeks for the best head development.

Feed it well
Little Gem grows best in rich, well-drained soil with a pH between 6.0 and 7.0. Work in 2 inches of compost before planting. Apply dilute liquid fertilizer every 2 weeks for steady head development. Adequate calcium prevents tip burn on inner leaves. Avoid excessive nitrogen which produces loose, floppy heads rather than the desired tight, compact form.
Ideal Temperature
Hardiness Zone Compatibility
From seed to harvest, stage by stage
Germination
Seeds germinate rapidly in cool, moist conditions, often within 2-5 days. The tiny white radicle emerges first, anchoring into the soil, followed by delicate cotyledon leaves that unfold to begin photosynthesizing. Lettuce seeds require light to germinate and should be sown on the surface or barely covered with a fine dusting of soil or vermiculite.
Seedling Development
True leaves emerge with the characteristic smooth, slightly cupped shape of romaine-type lettuce. Seedlings develop a shallow but fibrous root system. Growth is steady in cool conditions and the first hints of the upright growth habit appear as leaves begin to orient vertically rather than flat.
Rosette Formation
The plant rapidly produces new leaves from the central growing point, forming a tight upright rosette that is distinctly more compact than a standard romaine. Outer leaves darken to medium green while inner leaves remain lighter. The characteristic sweet crunch of Little Gem begins to develop as leaves thicken.
Heart Formation
The innermost leaves begin to fold tightly inward, forming the dense, blanched heart that makes Little Gem so prized. The outer wrapper leaves protect the heart from sun, creating a natural blanching effect that produces the pale, sweet, and exceptionally crunchy interior. The head firms noticeably when gently squeezed.
Harvest Window
Heads reach their ideal harvest size of 12-15 cm tall and 8-10 cm wide, weighing 150-200g each. The head should feel firm and dense when gently squeezed from the sides. Little Gem holds well in the garden for 7-10 days after reaching maturity before showing signs of bolting, giving a generous harvest window compared to many lettuce varieties.
Bolting
If not harvested, the central stem elongates rapidly as the plant transitions to flowering. The head loosens and opens, leaves become increasingly bitter, and a tall flower stalk emerges bearing small yellow daisy-like flowers. While the lettuce is no longer good for eating, the flowers attract beneficial insects and seeds can be saved for future planting.
Sow seeds no deeper than 3mm — lettuce is a light-dependent germinator and burying seeds too deep is the most common cause of poor germination. Keep soil consistently moist with a fine mist sprayer to avoid displacing tiny seeds.
Caring for Little Gem Lettuce month by month
What to do each month for your Little Gem Lettuce
July
You are hereThe most challenging month for lettuce in warm climates. Provide shade cloth (30-50% shade) during the hottest part of the day. Water deeply in the early morning. Little Gem tolerates heat better than most lettuces, but flavor is sweetest when grown in cool conditions.
Harvesting Little Gem Lettuce
Harvest Little Gem when heads are firm and compact, about 50 to 60 days after sowing. Cut the entire head at the base with a sharp knife in the morning. Each head is a perfect single serving size. Alternatively, harvest outer leaves individually starting at 30 days for a longer picking window. Do not wait until the center begins to elongate, which signals bolting.
assuming you sow when the window opens — set your real date
Pick Little Gem Lettuce promptly and the plant keeps producing.
Storage & Preservation
Little Gem heads store exceptionally well for lettuce, lasting 1 to 2 weeks in the refrigerator in a perforated plastic bag. Their compact structure helps them stay crisp longer than loose-leaf varieties. Do not wash before storage. Little Gem does not freeze or dry well. For the freshest supply, succession plant for continuous harvest throughout the growing season.
What goes wrong — and the fix
Slugs and Snails
PestHoles in outer leaves, slimy trails, and damage to the heart of the developing head.
Aphids
PestSmall green insects hiding in leaf folds, causing curled and distorted inner leaves.
Tip Burn
DiseaseBrown, papery edges on inner leaves, caused by calcium deficiency or uneven watering.
Troubleshooting Common Problems
Bolting from heat or long days causes bitter, elongated heads. Tip burn on inner leaves results from inconsistent watering or calcium deficiency. Slugs damage developing heads by hiding in the tight leaf folds. Aphids can be difficult to remove from the compact heart. Loose heads result from insufficient light or excessive nitrogen fertilization.
Growing Tips
- Succession sow every 2-3 weeks from early spring to late summer for a continuous harvest. A single sowing produces heads that all mature within the same narrow window, so staggering plantings is essential to avoid a feast-or-famine cycle.
- Sow seeds on the surface and press gently into the soil — never bury them. Lettuce is a light-dependent germinator and seeds covered by more than 3-5mm of soil will have dramatically reduced germination rates.
- If sowing in summer when soil temperatures exceed 25°C (77°F), pre-chill seeds in the refrigerator for 24-48 hours before sowing and sow in the late afternoon when soil is cooling. This breaks heat-induced dormancy that prevents germination.
- Space plants 15-20 cm apart in all directions for the most efficient use of space. Little Gem's compact upright habit means it needs significantly less room than a standard romaine, making it ideal for intensive raised bed planting and square-foot gardening.
- Maintain even soil moisture throughout the growing period — lettuce has a shallow root system and cannot draw water from deep soil layers. Irregular watering causes bitter flavor, tip burn on inner leaves, and premature bolting.
- Apply a thin layer of organic mulch (straw, grass clippings, or compost) around plants after transplanting to keep roots cool, retain moisture, and suppress weeds. In hot weather, mulch can reduce soil temperature by 3-5°C, significantly delaying bolting.
- Provide 30-50% shade cloth in summer heat to extend the growing season into warmer months. Little Gem is more heat-tolerant than most lettuces, but shade keeps roots cool and flavor sweet when temperatures exceed 24°C (75°F).
- Harvest the whole head by cutting at the base with a sharp knife, leaving a 2 cm stump. Little Gem can sometimes regenerate a smaller second head from the stump within 3-4 weeks, giving you a bonus harvest from the same planting.

Where Little Gem Lettuce comes from
Little Gem lettuce is a heritage variety that originated in England during the mid-1800s, where it was first cataloged as a compact, sweet-hearted lettuce ideal for small kitchen gardens. It is classified as a semi-cos (romaine) type, sitting uniquely between the butterhead and romaine categories with characteristics of both — the tender sweetness of a butterhead and the crisp, upright structure of a romaine. The variety quickly became a staple in British and French market gardens, where its compact size, reliable performance, and exceptional flavor earned it lasting popularity among both amateur gardeners and professional growers.
In France, where it is known as Sucrine, Little Gem became deeply embedded in bistro and home cooking traditions. French chefs prized it for its dense, naturally blanched hearts that could be halved and served as an elegant single portion — a presentation that remains a hallmark of French and Mediterranean salad courses to this day. The variety spread throughout Europe and eventually to North America, Australia, and beyond, though it remained relatively obscure in the United States until the farm-to-table restaurant movement of the early 2000s introduced it to American diners and home cooks.
Today, Little Gem enjoys worldwide popularity and is grown commercially across Europe, North America, and parts of Asia and Australia. In the United Kingdom, it consistently ranks as one of the top-selling lettuce varieties, outselling iceberg in many supermarket chains. Modern plant breeders have developed improved strains with enhanced disease resistance and even greater bolt tolerance, but the essential character of Little Gem — compact, sweet, crunchy, and perfectly portioned — remains true to the original Victorian-era variety that charmed English gardeners more than 150 years ago.
