Lettuce is hardy and can be planted as early as the soil can be worked. It's mostly a coolw eather crop and grows best in temperatures of 60-65 degrees.
This beautiful lettuce offers a large, open "head" of loose leaves that deepens in color as it matures. It is fast growing, heat tolerant, and slow to bolt! It will grow best in full sun but will also tolerate partial shade. The red color will come out more if the plant is in full sun during cooler weather
 
Head size (mature): 8-12 inches
Sun: Full fun, partial shade
