Organic 'Red Sail' Lettuce

Organic 'Red Sail' lettuce (Lactuca sativa) from the seed company Gaia, a tender red curly lettuce that is exceptionally slow to bolt

'Red Sail' lettuce is a heritage variety prized for its tender, decorative, ruby-red, crinkled leaves , which form loose, generous heads. Its soft, crisp texture makes it an excellent salad lettuce, while its high resistance to bolting allows it to remain in the field long after maturity—a major advantage for summer gardeners. It retains a fresh, pleasant flavor even in warm conditions, while displaying its most beautiful red hues in cooler weather.

Plant in partial sun/partial shade (level 2) with moderate watering (level 2). Space plants 15 cm apart, with 60 cm between rows.

Harvesting and preservation

Harvest at any stage—young leaves or formed buds—as the flavor is optimal after a few cool nights in autumn. For longer storage, keep the buds in sand in a root cellar at 1–2°C .
