Plants for Mangrove Swamps

The mangrove swamps feel really artificial currently due to the lack of biome-unique plants, here's a few ideas.

Papyrus Plant, just a nice looking plant.

Duckweed. This is a must have for swamps. It is a free floating plant which can grow on the surface of water in real life. It would look great and make the swamps feel more "swampy". But not only that, duckweed is actually edible in real life, so we can make it edible for the player in game.

Weeping Willow Tree. Right now the only tree that generates in the mangrove swamp is well, mangroves. The color of these trees resemble whitish greenish. It would be nice to have a greenish colored wood. The shape of these trees are really nice, too. It would fit in perfectly with the mangroves.
