Lettuce comes in a range of varieties – with flavors from buttery and mild to nutty and even slightly bitter; textures from delicate to crunchy; and colors from pale to dark green and burgundy.
With all these choices, even the most ardent veggie-phobes or demanding foodies will find lettuce to love. Most of the leafy greens we put in our salad bowls are varieties of Lactuca Sativa.
Lettuce can also be grown hydroponically - the growing of plants in nutrient solutions with or without an inert medium (such as soil) to provide mechanical support. Read our post on how to grow a soilless indoor farm for details.
Let’s take a tour of some of the best varieties of lettuce. We’ve included some popular choices for you to choose from, as well as some lesser-known cultivars.

How to Harvest Lettuce
Lettuce is one of the easiest and most straightforward vegetables to harvest, and most varieties can begin to be harvested between 30 and 70 days after planting, depending on the types of lettuce you’re growing. However, once harvested, lettuce is quick to wilt—so rather than harvesting all of your lettuce at once, simply visit your garden when you want fresh lettuce and harvest a little bit then.
1. Harvest the lettuce plants in the morning. Lettuce will be at its freshest in the morning before it has been out in the sun all day. Ignore this tip if you are growing hydroponically. If you want to harvest some of your lettuce, it’s best to choose and harvest your leaves before the temperature gets too warm and the lettuce begins to wilt.
2. Remove the outer leaves. The outer leaves of the lettuce plant are the most mature, so these are the ones you’ll want to harvest first. Look at the outer lettuce leaves and find any that are large, have a strong color, and feel crisp, and remove them by tearing gently or cutting with a pair of shears.
3. Allow the inner leaves to continue growing. Even though you’ve removed leaves from the lettuce plant, the inner leaves will continue to grow. Continue to care for the plant for later harvesting.
At the end of the season, if you’re harvesting lettuce plants all at once, simply cut the whole plant about a half-inch above the soil level. Harvested lettuce should be stored in the refrigerator in a loose, plastic bag and can keep for up to three weeks, depending on the variety.
