Little Gem is the perfect Cos Lettuce - it's quick to mature, dwarf and compact, producing crisp, sweet, medium-sized hearts. Resistant to root aphid. Suited to sowing March-July outdoors, and also good under cloches. RHS Award of Garden Merit winner. Cos Variety.   Heritage Seed Variety, 1938 packet details - A distinct and most valuable cos lettuce. Dwarf and compact in growth and a beautiful colour. The solid hearts, which stand for a considerable time before running to seed, are highly esteemed by those who prefer a small, crisp lettuce. Tom says: Quick and easy lettuces are many peoples first veggie crop. Try mixing red and green lettuce leaves to add a note of bitterness to salads, or try slicing up little gem lettuces and sautéing with peas and garlic for an alternative homegrown lunch.
