The term "wild oats" can refer to a couple of different things, but mainly it is known in two contexts: one related to plants and one related to behavior. Let's explore both meanings.
Plants: "Wild oats" refers to certain kinds of grasses that belong to the genus Avena, which are often found growing in the wild. These plants have tall stems and can produce grains that look similar to cultivated oats.
Behavior: In a more figurative sense, "to sow one's wild oats" means to engage in youthful, carefree, and often reckless behavior. This usually refers to a time in someone's life when they are exploring, partying, and not settling down.
"Wild oats" can refer to both a type of plant and a metaphor for youthful behavior.
