Lettuce Lassen is an upright romaine variety characterized by its dark green color and tight hearts. It is slow to bolt and performs strongly in heat, making it suitable for warmer growing conditions. This variety is extremely uniform and offers excellent tolerance to tipburn, ensuring quality heads throughout the growing season.
In addition to its heat resilience, Lassen provides outstanding protection against Fusarium, a common lettuce disease. Its consistent performance and uniformity make it a dependable choice for growers seeking a robust romaine lettuce that maintains quality under stress. This variety is ideal for both commercial production and home gardens where heat and disease tolerance are important.
