Buttercrunch lettuce can be planted just about anywhere, but the good news for those in warmer climates is that this variety tends to be far more heat-tolerant than most other lettuce cultivars. It has thick green leaves and small, tight head, 6 inch rosette that is fan-shaped rather than round It maintains its sweetness well when grown in the heat of summer.
Planting Direct Sow: seeds germinate at low soil temperatures, 40 to 60. Sow seeds 2 to 3 inches apart, rows 12 to 18 inches apart. Cover seed lightly, about 1/8 inch, and firm soil gently. Dry soil must be watered to ensure coolness and moisture, and for uniform germination. Holds well under stress and has good bolt resistance.
