Winter Lettuces are varieties of lettuces that can be sown late in the season, will tolerate cold and low light levels and still provide leaf pickings for the salad bowl right through winter and into spring. Some of my favourite lettuces are these hardy types because they have robust flavours, crisp leaves and good textures.
Lettuces mature in around 50-60 days when grown at optimum temperatures but the lettuce will slow down in cold weather, a trait which gardeners can use to their advantage. In cold weather a lettuce can stand fresh and ready to be picked for 2 or more months, it won’t go to seed and if you can protect the crop from very cold or wet weather and if you can get the timing right it will stand in perfect condition right through winter. So plan your winter crop of lettuce so that it is almost ready to pick by the first frosts of winter. At that stage it is large enough to stand light frost outdoors and undercover survive happily in surounding tempertures of -10c.
My pick of varieties
To get a good lettuce crop throughout winter it is best to select winter lettuce varieties, those that have proven themselves or been selected for thier growth habit and hardiness. My favourites include:
Winter Density (Cos) a lovely solid crisp green heading cos, standing tall and fairly tightly wrapped; excellent undercover in winter and outdoors in late winter/early spring. Rouge Grenobloise (Batavian) Large crispheads with red-tinted ruffled leaves, good flavour, cold hardy and will grow happily in shade; an excellent winter lettuce outdoors. Ubriacona (Loose Leaf Batavian) This Italian Heirloom has beautiful green hearts with red outer edged leaves, performs well and has great taste and texture. Provides cutting lettuce all year and will overwinter in my garden. Verde D’Inverno (Cos) Tall mid green heads crisp leaves with good taste. Stands well through winter. Rougette de Montpelier, (Butterhead) tight heading lettuce with crisp white stalks and soft green leaves tinged red at the edges, this variety can be grown undercover or outdoors but I find the flavour is better and the heads are crisper if grown outdoors. Valdor (Butterhead) I grew this lettuce for the first time 2 years ago so I am still testing it out and cannot thoroughly recommend it yet. It grew well in the polytunnel producing voluminous green heads with large fleshy leaves. But it suffered from mildew undercover, as spring approached and temperatures soured undercover, it may do better outdoors so I’ll give it another try this winter.
