romaine makes its way to the top. These elongated heads produce boat-like leaves made up of a crunchy midrib and tender green. Romaine is a key ingredient in Caesar salad, but it also works well for lettuce wraps and holds up to the high heat of a grill.

Growing romaine at home isn’t difficult, but it requires the right environment and the proper care. I’ll share how to start romaine from seed, transplant it into your garden, and care for it until it’s ready to harvest.
What Is It?
Also called cos lettuce, romaine is a general term for lettuce varieties with upright heads made up of elongated leaves. Like all types of lettuce, the easy-to-grow annuals thrive in cooler weather.

Characteristics
Romaine has an upright growth form and features thick and crunchy midribs that taper toward the tops of the leaves. These greens are tougher than other lettuce varieties, but they’re still tender enough to enjoy in salads.

The plants grow as vegetative annuals that thrive in the cool temperatures of spring and fall. Most varieties are deep green, but you can also find red cultivars.

Native Area
Romaine is native to parts of the Mediterranean and western Asia. While historians believe humans bred modern lettuce varieties from prickly wild plants, this is one of the oldest cultivated lettuces. People have been growing it for thousands of years!

Planting
These greens will grow well in well-draining soil in the ground, raised beds, and containers. The plants prefer cool weather, so spring and fall growing is ideal. However, with the right type of protection, you can extend the season into the summer and winter.


How to Grow
If you grow romaine in the spring and fall, it’s easy to care for. However, it’s more challenging to maintain healthy plants in the summer and winter.
Maintenance
Romaine lettuce doesn’t require much maintenance outside of regular care. Keep the soil moderately moist, remove weeds around the plants, and regularly check the growing plants for pests.
