Strapweed

Distribution:       

Strapweed or Posidonia is the only common seagrass in the Perth region, that appears ‘grass-like’. Growing from rhizomes that spread just below the surface of the sand, strapweed creates dense and extensive seagrass meadows. Seeds float to the surface during spring before sinking to the ocean floor to germinate. Strapweed often sheds its leaves each year, which are often seen floating on the surface and washed up onto the beach.
