These Oscarde Cutting lettuce seeds are certified organic and open pollinated. (30 days baby, 45 days mature) This lettuce is an industry standard. A beautiful mini oakleaf that grows low to the ground. Its red leaves shade to bright green at their hearts. These are perfect for greenhouse or tunnel cloches in cold weather. Always doing well in good conditions outdoors in spring and fall. You can cut it for a mesclun mix or baby leaf. Resists most races of DM. About 300+ seed per pack.  

Lettuce Culture: May be started indoors in March and at regular intervals thereafter, or sowed outdoors as soon as the ground can be worked. Many varieties won't germinate in soil temperatures above 75° and most shut down above 80°. Where available, we present data here from a California germination experiment at 84°.

Hardy. All lettuces except icebergs tolerate heavy frost. They grow best in cool weather with medium moisture. Use shade cloth to keep summer lettuce tender and sweet longer. 

Sow every 2 weeks for a continuous supply. Lettuce will not head unless thinned frequently and ruthlessly to a final distance of 1'. Heavy nitrogen feeders.

Minimum germination soil temperature 35°, optimal range 40-80°, optimal temperatures 70-75°. Emergence takes 3 days at 68°soil temperature.

Days to maturity are from direct seeding.
