Grand Rapids lettuce seeds grow into large green leaves that are resistant to tip burn. Ready to harvest in about 55 days, Grand Rapids thrives in full sun or partial shade, and can be grown in zones 3-12. The leaves of the Grand Rapids have a mildly sweet flavor.
Bred in the late 1800’s by Eugene Davis, known as the "father of forced lettuce,” Grand Rapids lettuce became the leading greenhouse-grown winter lettuce in the Grand Rapids, Michigan area. By the turn of the 20th century, these remarkably expansive greenhouses (over 150,000 square feet of them) were supplying millions of pounds of winter lettuce to the people of the Great Lakes region.
Grand Rapids lettuce is bright green, with wavy, frilled leaves. If left to mature it forms a head of loose leaves that reach 7 - 8” tall. It is very vigorous and bolt tolerant.
