Red Whipreed: Also known as Whisker-weed. This bright red, thick wetland reed plant infiltrates sewage systems and causes major damage to pipes and tunnels over time. The plant grows clones through root systems underground. Many cities put much effort into eradicating their Whipreed populations, and very few have succeeded due to the plant’s method of spreading. A whipreed stalk is flexible and firm, and can be used as a short makeshift whip, leading to the plant’s name.
Sucker Grass: This dark green short grass is well known for its ability to absorb the water out of a creature standing on it. An average sized humanoid could be fully dehydrated to unconsciousness due to this grass in less than 2 hours.
