Cimmaron Lettuce (Heirloom, 58 Days)
Heirloom – 1700’s. This Cos lettuce (romaine) is a unique bronze-red color, like no other we’ve ever seen. Its tall elongated leaves are hearty and delicious, and harvest can be conducted over a long period as it is slow to bolt. Cimmaron Lettuce dates back to the 18th century, but hasn’t been offered in this country for years. Our grower discovered some seed in a warehouse and a few were still viable, thus it was brought back on the market.
