Lettuce, Vulcan (Organic)
Lactuca sativa. Red Leaf. 50 days.
The unstoppable vivid Vulcan! Very early to mature with great taste for such a beautifully red lettuce. The tender durability, heat and disease tolerance have made Vulcan our red leaf lettuce of choice for many years. In fact, if we were going to plant one 300′ bed of red leaf lettuce, this is the variety we would choose, easily beating out New Red Fire and Red Sails. Good for organic farm production and/or home gardens. With moderate bolt resistance, be sure to plant in succession. Bred from a cross between Red Fire and a Korean red leaf variety. Introduced by Sakata Seed Company in 1987. The PVP expired in 2010. Yay!
Seed produced by Avoca in Corvallis, Oregon.
Sow indoors in flats with good potting soil year-round. Transplant into the garden 3-4 weeks after sprouting at 3″ spacing for leaf, 12″ for heads. 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.
