The Grand Rapids salad is an early-maturing semi-heading leaf lettuce variety known for its high yield and excellent taste. It features large, upright rosettes with a diameter of about 22 cm and a height up to 25 cm. The leaves are light green, thin, dense, glossy, with a finely bubbled surface and wavy edges; they possess a pleasant crunch and juiciness. Each plant weighs between 220 and 300 grams, making this variety particularly attractive for harvesting and fresh consumption.
Grand Rapids is distinguished by its resistance to adverse climatic conditions, leaf edge burn, and bolting, ensuring stable product quality and prolonged shelf life after harvesting. Thanks to these characteristics, the salad maintains its tenderness and appeal for an extended period, which is especially important for fresh marketing and consumption. This variety is suitable for cultivation in open ground as well as in various types of greenhouses, including film and light greenhouses.
This salad is valued for its delicacy and high vitamin content, making it in demand among farmers and consumers. The recommended planting density is 11–12 plants per square meter with a row spacing of 30x25 cm, ensuring optimal growth and development. The time from germination to technical maturity is about 47–50 days, allowing for an early harvest of fresh and nutritious produce.
