Redgrass

Redgrass is a rare species of grass that has red blades. This extraordinary coloration is the result of a rare pigment found within its cellular structure, which is metabolized through the minerals in the soil from which it grows. This not only gives the grass its distinctive color but also plays a crucial role in the specific photosynthesis, absorbing a different spectrum of light than its green counterparts.
  More intriguing is the phenomenon that occurs when Redgrass is cut or damaged. The grass exudes a thick, red liquid, remarkably similar in appearance to blood. This sap, rich in nutrients and minerals, is incredibly bitter and even poisonous to some animals. This forms a natural defense mechanism against herbivores and insects. However, traversing fields of redgrass will usually result in a gruesome appearance as if you had barely survived a battle or have been heavily injured. The similarity to blood has given rise to numerous local myths and superstitions, as there are even tales of entire fields suddenly turning to blood.   This liquid is used by some people as a natural pigment or paint, but other uses for the grass have not been found by alchemists or chemists. Additionally, attempts to transplant it to more common gardens have largely failed, as the grass seems to lose its vibrant colors when removed from its natural habitat.
