I must say I have not noticed this, but I don’t buy as much lettuce as I do other produce. Does this seem true of all lettuce that is red, regardless of variety? I am just beginning to explore the specifics of “not Romain”, especially versions of “little gem”.
Little Gem
Romain
Butterhead “Red Cross”
Merveille de Quatre Saisons ("Marvel of Four Seasons ". Looks better in French), also a butterhead. I grew this one last spring!
