Arthroceras subterminale is a species of flowering plant in the Amaranth family known by the common name Parish's glasswort. It is the only species in the genus Arthroceras. This coastal and inland California native plant is a shrub that is found southerly into northern Mexico, also in both coastal and inland areas, including salt marshes, alkali flats, and other habitats with saline soils. As a halophyte, capable of growing in substrates with high salt concentrations, this glasswort is a perennial herb or subshrub growing in low clumps up to a meter wide mature plants having woody bases branching into fleshy, jointed green stems. The leaves appear as fused rings around stem, the tip of each individual blade narrowing to a point. The inflorescence is a fleshy, sticklike spike of minute flowers, each flower just a pocket made up of the joined sepals; there are no petals.
Parish's glasswort is fairly resistant to disease and typically does not suffer from illnesses. Still, it can be affected by pests and pathogens present nearby. Such infections are usually minor. For care, the plant requires a moderate amount of maintenance. It should be pruned regularly to keep a neat appearance and support healthy growth. Fertilizing can also encourage flowering. Parish's glasswort is appropriate for anyone with an outdoor area, such as a garden or patio, and does not demand extensive care experience. It may need more attention if cultivated indoors.
How to keep Arthrocnemum Subterminale.
Light
Parish's glasswort is a sun-loving perennial herbaceous plant native to open habitats and commonly found in meadows and grasslands. It prefers full sun but can also tolerate partial sun.
Temperature
Parish's glasswort is highly adaptable to different climates, from blazing summers to cold winters. That said, it thrives within a specific temperature range. If temperatures become too high, the plant can suffer from heat and humidity stress, which may kill it. In areas where temperatures near its lower cold-tolerance limit, insulating the plant is necessary to protect it.
