Story of this Seed:

Called “Cos” lettuce in England. In Italian it is called lattuga romana and in French laitue romaine, both meaning “Roman lettuce,” an indication it arrive in Europe by way of Rome. Some language experts trace the word “cos” to the Arabic “khus.”

Cos or Romaine lettuce was associated with the ancient Egyptian god of fertility, Min. Romaine lettuce may be used in the Passover Seder as a type of bitter herb.

Growing Tips:

Silvia is better adapted to high temperatures than most lettuce, but is still likely to bolt if exposed to temps over 90 F for more than a week or so. In the West, especially in the Great Basin and lower deserts, Silvia is best grown in early spring and late fall.

Full sun and cool temperatures will intensify the burgundy color, and these conditions are desired for a full range of flavor. Shading and high temperatures will inhibit the red pigmentation and produce more of a bronze color and green fading.
