Panjin's Red Beach is a grass changing color
The "Red Beach" at Panjin, Liaoning, is not sand but a tidal flat covered in Suaeda salsa. The glasswort is tender green in spring; in autumn, as salinity rises and temperature falls, its anthocyanin increases and the whole flat burns crimson.
Suaeda grows in extremely salty mud as a classic halophyte, and the flat is habitat for red-crowned cranes and Saunders' gulls. Its red is not flowers but leaves — the color of a "beach" is a leaf's endurance boiled out of the salt.
