This variety of lamb's lettuce is cultivated on Reichenau island in Bodensee lake, near the Swiss border. This area is favorable for vegetable harvesting due to the island's oceanic climate with warm summers and lots of humidity. Feldsalat is frost-resistant, and it can be grown in greenhouses during the winter months and outdoors in spring.
It is hand picked here, unlike in other regions where it is usually harvested mechanically. After picking, it is gathered into 1-kilogram bunches. As a final product, the lettuce has small leaves, is free of roots, and is dark green in color. Reichenau island is also known as "vegetable island", as tomatoes and cucumbers of extraordinary quality are grown there.
