Agropyron is a Dianthus plant. It is called Agropyron cristatum because there are a lot of cell bubbles on its stems and leaves. Cell vesicles store a large amount of liquid, which is like ice under the reflection of solar light, so it is called wheat straw. Its cell vesicles contain a small amount of salt, so there is no need to put salt when eating. The taste is slightly salty, fresh and juicy.

Agropyron cristatum is a unique vegetable in Africa, which later spread all over the world. It is also cultivated in many places in China. Agropyron is also called wild wheat, crystal ice cream, ice cream, icicles and so on. It is called ice cream not because it can be frozen, but because there are a lot of bubble cells on its leaves and stems, which contain liquid. At first glance, it looks like frost.
