The Denver lettuce is a late-maturing head lettuce of the Iceberg type, featuring high yield and adaptability. The plant forms a rosette of semi-erect leaves about 25 cm high, with a greyish-green hue and slight ruffling at the edges. The head of this variety is flat-round, dense, and closed, with a crisp leaf texture and excellent taste. Thanks to its slow filling rate, the variety provides more time for harvest, which is particularly valuable when growing in spring and autumn periods.
Denver is characterized by high resistance to bolting, allowing for more standard heads, and also possesses resistance to various diseases, including sclerotinia (false powdery mildew) and lettuce mosaic virus. This plastic variety is successfully grown both in open ground and in closed facilities, demonstrating all-season suitability and a long shelf life after realization. Its attractive appearance and superior taste qualities make it in demand for various growing purposes.
The variety is characterized by high plasticity and wide adaptation capabilities to climatic conditions, allowing its use in various agrotechnical systems. Plant density is 70,000 – 80,000 per hectare, which contributes to optimal crop formation. Due to the combination of qualitative characteristics, disease resistance, and ease of cultivation, Denver lettuce is an excellent choice for professional agrarians and gardening enthusiasts.
