Lobelia chinensis, commonly known as Chinese Lobelia, is a deciduous perennial herb native to marshlands and along streams in East Asia, including China, Japan, Korea, and Vietnam. It typically grows to a height of 0.3-0.5 feet and spreads 1-3 feet wide. The plant features delicate, tubular flowers that are usually a combination of pink and white, blooming in the summer and fall. These flowers are not particularly showy but add a subtle charm to water garden settings. The foliage is lance-shaped and can provide a lush green ground cover. Chinese Lobelia is known for its medicinal properties, traditionally used in Chinese medicine, and is harvested for its stems and roots.

In cultivation, Chinese Lobelia is appreciated for its adaptability to wet conditions, making it suitable for water gardens, bog gardens, and as a marginal aquatic plant. It thrives in full sun to part shade and requires consistent moisture, tolerating a range of soil drainage types. While it is mildly toxic, it is not typically a concern unless ingested in large quantities. Gardeners should be cautious when handling this plant, especially around pets and children. It is not commonly afflicted by diseases but can suffer from root rot if drainage is poor.CC BY-SA 4.0
