Glechoma

Glechoma is a genus of perennial flowering plants in the mint family, Lamiaceae. The genus is native to Europe and Asia, but has been introduced to many other parts of the world. The most well-known species is Glechoma hederacea, commonly known as ground-ivy or creeping charlie.

Glechoma species are typically low-growing, creeping plants that spread by stolons. They have rounded or kidney-shaped leaves that are arranged oppositely along the stem. The leaves are often aromatic, with a scent reminiscent of mint. The flowers are small and tubular, usually pale purple or pink, and appear in whorls in the leaf axils.

Glechoma hederacea is often considered an aggressive weed in gardens and lawns due to its rapid growth and ability to outcompete other plants. However, it has also been used in traditional medicine for its purported diuretic and expectorant properties. Historically, it was also used as a flavoring agent and fining agent in brewing.

Other species in the Glechoma genus include Glechoma hirsuta and Glechoma lobulata, though these are less common and have more restricted native ranges. The genus is characterized by its creeping habit, aromatic foliage, and characteristic flower structure.
