Dunand by Rijk Zwaan is dark green crystal lettuce for year-round production on hydroponics systems and soil medium. It grows very upright with straight veins, which makes it less brittle and easy to handle. It is also suited to grow with 3 seeds in a pot. Crystal Lettuce is comparable to open iceberg lettuce and suitable for all year-round cultivation.  Dunand produces a high yield of juicy, sandwich-sized leaves with a sweet taste and very crunchy bite, ideal for use in the gastro and catering industry. The dark green Crystal Lettuce Dunand is strong against twisted veins and elongation as well as bolting, tip burn, and leaf breakage. >Upright growth, small cutting area, high yield >Crispy sandwich-sized sheets, long shelf life >Strong against bolting, tip burn, and blade breakage >Variety: Green Crystal >Adaptability: Good for Lowland, Midland, and Highland, Heat Tolerant >Germination: 95% and up >Maturity: 30 - 35 Days After Transplanting >Origin: The Netherlands
