Lettuce - Cos
Cos Lettuce in my vegetable patch.
Cos does not hold for long in the ground as it tends to go to seed after a fairly short space of time. It also does not have quite as fine a texture as an icicle lettuce, such as Great Lakes. However it is less susceptible to slug and snail damage and is less likely to get the disease Downy Mildew , which regularly strikes icicle lettuces. Cos makes a good substitute to icicle lettuces, specially in the warmer weather when Downey Mildew is likely to be more active.
