Arthroceras subterminale, commonly known as Parish’s glasswort, is a perennial herb or subshrub native to coastal salt marshes, alkaline flats, and saline soils within the coastal and inland regions of California and northern Mexico. It typically forms low, spreading clumps that can reach up to 3 feet in width. Parish’s glasswort is a halophyte, meaning it is well-adapted to environments with high salt concentrations, and it displays fleshy, jointed green stems that are characteristic of plants in saline habitats.

Parish’s glasswort is valued for its ability to thrive in challenging saline conditions, making it an important plant for habitat restoration and soil stabilization in its native range. It is also used in ornamental saline gardens and can be a unique addition to water-wise landscaping. In cultivation, it requires full sun exposure and well-drained soils that mimic its natural saline environment. While it is drought-tolerant, it can also tolerate periodic flooding, especially with saltwater. This plant is relatively low-maintenance, but gardeners should be aware that it may not be suitable for all garden settings due to its specific soil salinity requirements.CC BY-SA 4.0
