'Ice Queen' dates back to 1883, and gets its name because it is cold tolerant, but also tolerates heat well and is slow to bolt. This bright, emerald green lettuce with frilly leaves has crisp texture and excellent fresh flavor. Also delicious as a baby green. Once leaves have been cut, plants continue to grow.
