1 packet contains 100 seeds Lettuce. Lettuce greens are so easy to grow, so nutritious, and so delicious picked fresh from the garden, that everyone should grow them. Grow lettuce in the vegetable garden, tuck it into flowerbeds, or cultivate it in containers. With regular watering, shade from hot sun, and succession planting, you can enjoy home-grown lettuce almost year-round in much of the country. From baby leaf lettuce to big, crisp heads, lettuce is easy to grow in spring and fall, when the soil is cool. Leaf colour and texture vary with variety. All types of lettuce grow best when the soil is kept constantly moist, and outside temperatures range between 45 and 75 degrees Fahrenheit.
