Lettuce is a common vegetable in our life. It is widely planted in my country. It has a long history of being introduced into my country and has been cultivated and cared for very early on.

2. Different shapes

Western lettuce is also called ball lettuce. From the name, we can see that its shape is cylindrical, conical, oblate, round, etc. It looks like an elliptical sphere with leaves wrapped around the sphere. Moreover, its bottom is a taproot system, the soil layer is relatively shallow, and the roots are not deep, so its absorption capacity is greatly weakened during maintenance.

The shape of the lettuce is outward-expanding, and it is not rolled into a ball like the former. The surrounding leaves are more wrinkled and arranged irregularly, which looks rather messy. Some leaves are flat, while others are wrinkled. There are also wavy patterns or shallow cracks on the edges of the leaves, and the outer leaves are spread outwards.
