boll

A boll is the protective, rounded seed vessel of plants like cotton and flax—think of the fluffy white puffs that form in warm fields. While the term is primarily used in agriculture, it can also refer, in older regional usage, to a rounded swelling or knob. In the Southern United States, the term is strongly associated with cotton history, especially through the boll weevil, a pest that once devastated crops and local economies. Think of it as nature’s own packing case, designed to protect seeds and fibers until harvest.

The word boll primarily refers to the rounded capsule or pod that contains the seeds of plants such as cotton, flax, or hemp. In crops like cotton, this pod develops on the plant, matures, and eventually opens so the fibers and seeds can be harvested for textile use.

Beyond botany, older or regional uses can include a rounded lump, swelling, or knob, though these senses are uncommon in modern English. The term is linked historically with cotton production in the American South, where it appears in discussions of agriculture, labor, and trade that shaped modern textile history. Whether you are reading about a farm cycle or older regional writing, boll usually points to a rounded seed structure and the language that grew around it.
