Bachelors-in-the-grass is a type of dianthus ("pink"), albeit a Discworld cultivar favored by the likes of Nanny Ogg. While most pinks are perennial herbs, a few are annual or biennials. Most species have flowers of pale to dark pink. The flowers of dianthus are edible, with uses primary as decorative splashes of color in salads.
Tall and bearing brightly covered blossoms, Bachelors-in-the-grass never grow in clusters of more than three. The colouring of the flowers becomes more garish as the plant ages. The bitter, dry taste makes it unpalatable for most animals.
It is not poisonous to eat. However if one does eat it, the result will be a very short bout of hallucinations. The hallucinations are even clean, which is very surprising given who grows it.
