Kagraner Sommer
Planting Schedule
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.
