Lactuca sativa var. crispa

vegetable

Red Sails is a loose-leaf lettuce variety known for its deeply ruffled, burgundy-red outer leaves that transition to green toward the center. It offers mild, tender leaves ideal for fresh salads and has attractive ornamental appeal. This heat-tolerant variety resists bolting better than many other lettuces, making it suitable for extended harvests.

Growth Stages

1

Germination

7-10 days

Seeds sprout and tiny seedlings emerge with first true leaves visible within 7-10 days.

Keep soil consistently moist but not waterlogged. Maintain temperatures 60-70°F for best germination. Provide light once seedlings emerge.

2

Seedling

2-3 weeks

Young plants develop 2-3 true leaves and establish a shallow root system. Leaves are still tender and mainly green.

Thin seedlings to proper spacing when they have 2-3 true leaves. Water gently to avoid damaging tender growth. Keep soil consistently moist.

3

Vegetative Growth

2-3 weeks

Plant develops characteristic deeply ruffled leaves; red coloration becomes more pronounced on outer leaves. Rosette shape forms.

Maintain consistent moisture and moderate temperatures (55-70°F). Begin light fertilizing every 2-3 weeks with balanced or high-nitrogen fertilizer. Remove any yellowed outer leaves.

4

Leafing Out

1-2 weeks before first harvest

Full rosette forms with abundant deeply ruffled burgundy-red outer leaves and tender green inner leaves ready for harvest.

Continue consistent watering. Monitor for pests. Begin harvesting outer leaves once plant reaches desired size. Watch for early bolting signs in hot weather.

5

Harvest/Extended Picking

2-4 weeks (cut-and-come-again harvesting)

Mature plant produces a full canopy of harvestable leaves; red coloration is most vibrant. Inner leaves remain tender and mild.

Harvest outer leaves regularly to encourage continued production. Keep soil consistently moist. Provide afternoon shade if temperatures exceed 75°F. Plant may bolt if exposed to prolonged heat.

Harvest Tips

Begin harvesting outer leaves when plant is 4-6 inches tall, about 30-40 days after planting. Use the cut-and-come-again method: pinch or cut outer leaves from the base, leaving inner rosette intact for continued growth. For full-head harvest, cut entire plant 1 inch above soil line. Morning harvest yields crispest leaves. Red Sails can be harvested for 4+ weeks with proper care. Do not harvest more than 1/3 of the plant at once when using cut-and-come-again method.

Fun Facts

  • 🌱 Red Sails was developed and introduced by Burpee Seeds and has become one of the most popular red loose-leaf varieties for home gardeners due to its reliable heat tolerance compared to other lettuces.
  • 🌱 The deep burgundy-red color of the outer leaves develops more intensely in cooler temperatures and direct sunlight, while the same plant grown in shade will appear predominantly green.
  • 🌱 Red Sails can be harvested continuously for 4-6 weeks or longer using the cut-and-come-again method, potentially yielding more total leaves per plant than heading lettuces.
