Growing habits:
Silver convolvulus is a typical xerophyte, and its pH value is 8.0 ~ 8.5, and it can grow when it reaches 9. It is a common companion species of saline-alkali grassland and various grassland communities. Like dry and well-drained habitats, the number of grassland degradation and salinization increases. It is an indicator species of grassland degradation and salinization. In degraded and salinized grassland, it can become the dominant species in the lower layer, and in local alkali bag, the grass in the upper layer can also become the dominant species after disappearing, forming a small community.
