What plants are typical for the steppe zone?

The steppe zones in all climatic zones are characterized by the dominance of herbaceous vegetation. First of all, these are cereals. However, trees are also found, although rarely. In the steppes of tropical zones (pampa in South America, savannah in Africa), the grass can reach a height of more than a meter, since it is hot here and there is a lot of rainfall during the rainy season. But in the northern or real steppes, the grass is undersized, since there is little rainfall, and the winter is long and cold.
