Klammath Weed - English Definition & Meaning

Definition

"Klammath weed" is a common name for *Hypericum perforatum*, also known as St. John's wort. This plant is an invasive species in many parts of the world, particularly in North America. It's characterized by its bright yellow flowers and small, translucent dots on its leaves. Historically, it's been used in herbal medicine to treat depression and wounds. However, it can also be toxic to livestock, causing photosensitivity. So, while it has some benefits, it's also considered a problematic weed.

Etymology

"Klammath weed" gets its name from the Klamath River region in Oregon and California, where it became a significant problem. *Hypericum* comes from the Greek words "hyper" (above) and "eikon" (picture), possibly referring to the plant's use in hanging above images to ward off evil. *Perforatum* refers to the small, translucent dots on the leaves that appear as perforations. St. John's Wort is named because it typically blooms around St. John's Day (June 24).
