Pandanus or wild pineapple is the environmentally friendly alternative to seagrass, a plant which grows in warm coastal waters. When coiled and woven, it’s almost indistinguishable from seagrass. Seagrass grows predominantly in shallow waters. It is home to many nursery fish and helps to prevent coastline erosion. Seagrass is therefore an incredibly important plant which needs to be conserved. Pandanus, on the other hand, is a prolific and fast growing plant which is easy to sustain.
