Euphorbia serpens
Its stems are slender, smooth, and extend radially from a central root system, forming dense circular mats that can range from a few centimeters to half a meter in diameter.
By growing flush against the ground, beach sandmat reduces the surface temperature of the lava substrate and retains moisture beneath its leaves — creating favorable microhabitat conditions for soil microorganisms.
It is a fast-growing plant capable of germinating, flowering, and releasing seeds within a very short period, capitalizing on the temporary moisture available on rocky surfaces.
