The present invention relates to a head-forming lettuce plant of the species Lactuca sativa having red leaves throughout the head, including the heart. The red leaves in the heart are red even in the absence of radiation with wavelengths shorter than 400 nm, wherein the absence of radiation with wavelengths shorter than 400 nm is in the growing environment during the complete period from sowing until observation. The ratio between anthocyanin and chlorophyll lies between 4 and 50, preferably between 9 and 27. The invention also relates to progeny of the plant.
