The Rolina variety is a Batavia type lettuce. The plant is characterized by specific accumulation of anthocyanins and chlorophyll in the leaves, which makes it a subject of study in works dedicated to the influence of light conditions and temperature on the pigmentation of the leaf apparatus.
In public materials, the variety is mentioned as a red-leaf lettuce cultivar. Detailed agronomic data, such as precise maturity dates, plant parameters, or a complete resistance profile to specific pathogens, are presented fragmentarily in open sources.
