Salad leaves, such as lettuce or spinach, typically produce a single seed head containing multiple seeds. Depending on the variety, a single plant can produce hundreds to thousands of seeds.

Preventing lettuce from going to seed in the garden is important because once lettuce goes to seed, the leaves become bitter and the plant stops producing new leaves. This reduces the quality and quantity of the lettuce that can be harvested for consumption.
Lettuce is classified as an angiosperm. Angiosperms are flowering plants that produce seeds enclosed within a fruit, while gymnosperms are seed-producing plants that do not form flowers or fruits. Lettuce belongs to the family Asteraceae and reproduces by flowering, making it part of the angiosperm group.
