Description

Isodon longitubus

Isodon longitubus, commonly known as Korean mint bush, is a distinctive perennial herb belonging to the Lamiaceae family. This aromatic plant typically reaches heights of 60-120 centimetres, forming dense, upright clumps with square stems characteristic of the mint family. The species produces small, tubular white or pale purple flowers arranged in terminal spikes during late summer and autumn.

Native to East Asia, particularly Korea and parts of China, this hardy plant has gained popularity in British gardens for its drought tolerance and late-season flowering. In traditional Korean medicine, various Isodon species have been valued for their therapeutic properties. The plant thrives in well-drained soils and partial shade, making it an excellent choice for woodland gardens or naturalised plantings. Its robust nature and ability to attract pollinators have made it increasingly sought after by UK gardeners seeking low-maintenance, wildlife-friendly perennials.
