Crisp, buttery leaves unfurl in a soft, luminous rosette—Kagraner Sommer butterhead lettuce is prized for its tender, sweet flavor and delicate, velvety texture. At maturity, the heads form a gentle, spoon-shaped heart with pale green to creamy tones that feel as good as they taste. Grow it for fresh salads and elegant garnishes, or let its mild, mellow character shine in quick summer bowls and light sauces.

Frequently Asked Questions


How often should I water Kagraner Sommer during the main growing phase (around weeks 3–6)?
Keep the top 1–2 inches of soil evenly moist so leaves grow tender and fast, aiming for consistent moisture rather than cycles of drying and soaking. In typical home beds, that often means watering about 1–2 times per week, increasing to more frequent watering during warm spells. Stop short of waterlogged soil—lettuce in soggy ground is prone to rot and disease.
How can I tell when Kagraner Sommer is ready to harvest at about 55 days?
Harvest when heads/rosettes are fully sized for your thinning plan and outer leaves are crisp and firm, usually around 55 days from sowing. For leaf-style lettuce, pick outer leaves once they’re large enough to eat; don’t wait until the plant bolts or becomes bitter. If you see a tall central stalk or leaf bitterness increases, harvest immediately or the quality will drop fast.
