Another showy lettuce from Wild Garden Seed where they say this about it:
"The most intensely pigmented and deeply savoyed lettuce we sell. Very dark purple-red leaf/semi-cos heads with gorgeous rumpled and puckered hearts. An eye-catching standout in trials from Maine to Philomath High for summer color and autumn cold hardiness. High scores for resistance to Sclerotinia and downy mildew in '02 and '03 disease plot trials Farm Original Variety! OSSI (Open Source Seed Initiative) Pledged Variety."
