Do lettuce plants keep producing?

When mature plants begin to set lettuce seed like this it is called “bolting” in gardening circles. When you see this happening — a sturdy seed stalk will emerge from the center of the plant — stop harvesting.
Does lettuce regrow every year?

What happens when lettuce bolts?
When plants flower, it’s generally considered a good thing; however, in vegetables grown for their leaves, such as lettuce, spinach, cabbage, and other cole crops, bolting causes the flavor to turn bitter and the leaves to get smaller and tougher, making them inedible.
