Quick facts

About Mediterranean saltwort

Arthrocaulon macrostachyum, also known as Arthrocnème à gros épis or Salicorne à gros épis, is a succulent halophytic plant that thrives in saline environments. It has a low, highly branched shrub-like appearance with articulated green stems that can take on reddish hues under stress conditions. It is ideal for coastal gardens, saline rockeries, or as an ornamental potted plant in sunny areas.

Native range

Mediterranean region (Southern Europe, North Africa, and the Middle East)

Care tips

This species requires full sun for optimal growth and prefers sandy or silty soils with good drainage, tolerating high levels of salinity. Watering should be moderate, allowing the substrate to dry completely between waterings, as excess moisture can be detrimental. A common mistake to avoid is overwatering, especially in winter, which can lead to root rot. It does not require regular fertilization.
