What Is a Corn Broom Made Of? | The Real Bristle Breakdown

That name is where the confusion starts. Despite the label, a corn broom has no corn cobs or kernels in it. Broomcorn is a type of sorghum grown specifically for its stiff, fibrous tassels — the part that becomes the bristles you sweep with. It’s been the standard material for quality brooms in the United States for generations, and it’s still what most commercial corn brooms use today.

The rest of the build is simple: those broomcorn fibers get soaked to become pliable, layered around a wooden handle, and then compressed and bound tight with cord or twine. The flat, fan-shaped end you sweep with is trimmed flat after the bundle is secured. That’s the whole formula.

Is It Really Made From Corn?

No — not the corn you eat. Broomcorn is a member of the sorghum family, not the sweet corn or field corn you’d find in a grocery store or farm field. The plant is grown for its long, brush-like seed heads, which dry into stiff fibers perfect for sweeping.

People commonly mix the two up because of the shared name. If someone tells you a corn broom is made from corn cobs, that’s the myth. The bristles are the plant’s tassel, and the handle is almost always a separate piece of wood.

Broomcorn vs. Blends: What’s Inside Matters

Here’s where it gets interesting. Not every “corn broom” on the shelf is 100% pure broomcorn. Some are blends that mix in other natural fibers such as sotol or rattan. A manufacturer might label a model as 85% broomcorn and 15% sotol, or another as fully 100% natural broomcorn with no filler grasses. Both are sold as corn brooms.

That distinction matters for how the broom performs. Pure broomcorn is flexible, durable, and works well for both wet and dry sweeping. Filler grasses, the argument goes, are more prone to rot when they stay damp. Some commercial manufacturers specifically note that their all-broomcorn models are built for wet or dry use, while the blended versions may not hold up as well in moisture. This is a manufacturer claim rather than a universal standard, but it’s a useful one to keep in mind if you plan to use the broom on a damp garage floor or patio.

How the Broom Gets Assembled

Making a corn broom is a hands-on process rooted in traditional American broom making, and the steps haven’t changed much over the decades. The broomcorn is first gathered and soaked in water so the fibers become soft enough to work with. Once pliable, the stalks are layered around the wooden handle in a tight bundle.

From there, the bundle is compressed and bound. The binding is typically nylon twine or hemp string, depending on the maker. Some handmade brooms are also stitched through the flat head to keep the fibers from splaying out of shape. Finally, the swept end is trimmed flat to create that recognizable broom shape. If you’re making one at home, this process involves sharp cutting tools and water handling, so the usual precautions apply.

FAQs

Why is it called a corn broom if there’s no corn in it?

The name comes from broomcorn, a type of sorghum plant grown specifically for its stiff seed-head fibers. The plant belongs to the sorghum family, not the edible corn family, but the shared “corn” in the name stuck. The broom’s bristles come from that plant’s dried tassels, not from corn cobs or kernels.

Are corn brooms good for wet surfaces?

Pure broomcorn brooms handle wet and dry conditions well, per some commercial manufacturers. The caveat is blends: brooms that include filler grasses like sotol or rattan may not hold up as well in moisture and could rot over time. Check the label for whether the broom is 100% broomcorn or a blend before using it on damp surfaces.

What’s the difference between a corn broom and a regular broom?

A corn broom uses broomcorn fibers as its bristles, while a regular broom typically uses synthetic materials like plastic or polypropylene. Corn brooms are natural, biodegradable, and have a stiffer but more flexible sweeping action. They also wear out faster than synthetic brooms and are not ideal for ultra-fine dust on hard floors.
