|'Aleppo', also known as 'Spotted Cos' is an heirloom variety of lettuce dating back to the 17th century. It is a short romaine lettuce with bright green leaves which have a slightly floppy habit. The leaves are savoyed and speckled with reddish brown spots. A well-grown head generally measures 16 inches across. Start from seed 4 to 6 weeks before average last frost date. Sow seeds 1/4 inch deep in wide rows and thin to 8 to 12 inches apart. Thinned seedlings can be replanted. Keep soil moist but not soggy. Protect from rabbits and slugs. Extend the harvest season by planting successive crops. Summer heat causes lettuce to bolt. Pick outer leaves as they grow or harvest all at once. Harvesting when weather or day temperature is cooler will result in crisper leaves. Do not harvest lettuces until you are ready to use it.
