Why Green Beans Are a Little Fuzzy

Ever noticed that green beans are a bit... hairy? Those fine hairs are called trichomes, and they’re not just for looks—they’re part of the plant’s natural defense system.

Trichomes make the bean’s surface rough and unpleasant for insects to crawl on. Some even trap bugs before they can nibble on the tasty bean inside. Think of it as built-in bug repellent.

Other Hairy Veggies? Yep.

• Cucumbers have rough, prickly skins that bugs avoid.

• Tomatoes grow sticky trichomes that trap pests like tiny flypaper.

• Zucchinis sport scratchy little hairs for the same reason.

It’s all part of nature’s clever pest control—no sprays required.
