Just like the names indicate, sea and sand spurrys are found in salty or sandy soils. The salt sand spurry grows on saline ground high up on the salt marsh where it rarely floods. Greater sea spurrey grows lower down on the marsh, where it risks the chance of being flooded. However, this plant has an ingenious method for suriving such a salty bath. As the water rises, the petals will close and retain an air bubble to keep the pistil and stamens dry.
