Lactuca sativa var. crispa
vegetableRed Sails is a loose-leaf lettuce variety prized for its deeply frilled, burgundy-tipped leaves and mild, tender flavor.

Vegetative Growth
20-30 daysPlant develops multiple deeply lobed and frilled leaves arranged in a loose rosette; leaves show increasing burgundy coloration at edges
Maintain consistent moisture and cool temperatures; fertilize every 2-3 weeks with balanced fertilizer; ensure good air circulation to prevent fungal issues
Leaf Development & Maturation
15-20 daysRosette fills out with numerous large, heavily frilled leaves displaying deep red pigmentation; plant becomes full and ornamental
Begin selective harvesting outer leaves; continue regular watering and fertilizing; watch for bolting if temperatures rise above 75°F
Harvest-Ready
Ongoing throughout seasonPlant reaches desired size (8-10 inches across) with abundant, tender, colorful leaves ready for cutting
Harvest regularly using cut-and-come-again method to encourage continued leaf production; harvest in early morning for crispness
Bolting (End of Season)
Variable; 1-2 weeksPlant begins to elongate and flower as temperatures warm or day length increases; leaves become more bitter

Harvest Tips
Begin harvesting outer leaves when plant is 4-6 inches tall (30-40 days) using the cut-and-come-again method; gently cut or pinch leaves 1-2 inches above soil line; harvest in early morning for maximum crispness and moisture content; continue harvesting until plant bolts or temperatures become too warm; entire plant can be cut at soil level for a final harvest
Fun Facts
- 🌱 Red Sails was developed by Alf Christianson at Christianson Seed Company in the 1980s and has won the All-America Selections award for its combination of beauty, flavor, and performance
- 🌱 The burgundy-red coloration in the leaf edges develops more intensely in cooler temperatures and with exposure to sunlight, making fall-grown lettuce more colorful than spring plantings
- 🌱 Unlike head lettuces, loose-leaf varieties like Red Sails can be harvested continuously for weeks by using the cut-and-come-again method, providing fresh greens throughout the growing season
