About Perennial glasswort
Salicornia perennans, also known as perennial glasswort or spreading glasswort, is a halophytic succulent plant thriving in salt marshes and coastal areas. Its segmented, fleshy stems, ranging from bright green to reddish, give it a unique and sculptural appearance. It is ideal for coastal gardens, saline rockeries, or as an ornamental potted plant, providing an exotic and low-maintenance touch.
Native range
Coasts of Europe and North Africa, from the Baltic Sea to the Mediterranean and Black Sea.
Care tips
It requires full sun for optimal growth and tolerates soil and air salinity well. Watering should be moderate, allowing the substrate to dry out between waterings, and it's crucial to avoid waterlogging. It thrives in sandy, well-drained substrates, preferably with a saline or brackish component. A common mistake is overwatering or planting it in poorly drained soils, which can lead to root rot.
