ROMAINE / COS Lettuce Seeds
Lactuca sativa (Open Pollinated)
Long-acclaimed as the "Caesar Salad lettuce," Romaine produces dense pointed heads of sturdy, upright leaves with exceptionally crunchy midribs. Like most lettuces, Romaine prefers relatively cool weather. Sow every two weeks through early summer, starting as soon as the ground can be worked in the spring. For fall planting, start seeds mid-summer in cool climates - or towards the end of summer in areas with considerable heat.
