Grand Rapids Lettuce is a popular and well-loved variety of loose-leaf lettuce, known for its quick growth and suitability for a variety of gardening situations. This variety is particularly suited for cooler weather, thriving best in temperatures between 12 C- 21C. It’s a versatile choice for both container gardening and small garden spaces.
This lettuce is distinguished by its bright green color, with wavy, frilled leaves. When allowed to mature, Grand Rapids lettuce forms a head of loose leaves. It is an heirloom variety that dates back to the 1800s and is appreciated for being slow to bolt, meaning it can be grown later in the spring compared to other varieties.
When it comes to cultivation, Grand Rapids lettuce can be directly seeded outside 3-4 weeks after the last frost date, or it can be started indoors in trays or pods about 6 weeks before the last frost. It prefers well-draining soil rich in organic matter and full sun, although it can tolerate partial shade. Regular watering is essential to keep the soil evenly moist. The lettuce is generally ready to harvest in about 45 days for full leaves, or earlier for baby lettuce.
The Grand Rapids lettuce variety was bred in the late 1800s by Eugene Davis, who was known as the “father of forced lettuce.” This variety became a leading greenhouse-grown winter lettuce in the Grand Rapids, Michigan area. The development of Grand Rapids lettuce by Eugene Davis marked a significant advancement in the cultivation of lettuce, especially for greenhouse production during colder months.
