Bladder Wrack or Popweed Seaweed

If you get a chance to visit the coastal region at all then do not let the opportunity to harvest some coastal delights pass you by. The coast is an abundant source of food rich in nutrients and should not be passed over. Seaweeds are all year round but are at their best in April, May and June.

Bladder Wrack is easy to identify because it grows with small to large sacks of gas, it’s name comes from the inflated bladders they possess. You may recall stepping on this seaweed as a child and having hours of entertainment from the popping sounds – much like bubble wrap. Bladder Wrack (or popweed) is also abundant in the UK and if you find nothing else, you will find this.


Small Bladder PopweedRemember to only cut seaweed that is attached and living on rocks, avoid seaweed that is floating free. Cut at the stipe (the hard stem like part) giving a good distance away from the section that holds the seaweed to the rock, this will allow the seaweed to regrow without too much trouble.

Wash the seaweed thoroughly before use to clean it of contaminants and excess salt. Avoid seaweed that grows near Red Tide (the red algae) and other high pollutant areas.
