Lettuce, Bríwerí (Organic)
Lactuca sativa. Green Butterhead. 50 days.
Light-green butterhead, bred for greenhouse and cold frame forcing in winter and spring. Quick to size up in cold conditions, we have planted it outdoors under row cover in spring and in fall with great results. Excellent variety sourced from the German biodynamic seed company, Bingenheimer Saatgut. They recommend sowing in late November in an unheated hoophouse for April harvest. Resistant to DM races 12, 17, 18, 22, 24, 25. Bred by Richard Specht with support from Kultursaat, a German Foundation dedicated to advancing open pollinated varieties.
Sow indoors in flats with good potting soil year-round. Transplant into the garden at 1′ spacing 3-4 weeks after sprouting. Alternatively, direct sow March through September. In our area, lettuce can go through winter if protected. Succession sow for continual harvest.
Collect seeds when flowers are downy like dandelions. Cut seed heads and place upside down in a bag to dry for a few days. Knock seed heads against side of bucket or tote, rub downy fluff off seeds. Winnow and screen to clean.
