Salicornia europaea is an annual succulent with much-branched and fleshy stems that grow up to 16 inches (40 cm) tall. Leaves are the part that you see. They are like tubes surrounding the stem and extend from one stem-joint to the next. It is in flower in late summer, and the seeds ripen in fall. Flowers are tiny and hermaphrodite (have both male and female organs).

It is grown as an annual plant, so it has no USDA hardiness zone.

How to Grow and Care

Glasswort prefers fertile organic soil with ample nitrogen and regular watering. This species is little if at all, cultivated, and its exact requirements are not clearly understood. It is not known if the plant will require periodic inundation by salty water to grow well.

This plant is difficult to grow in cultivation. It can succeed in gardens if sown as soon as the seed is ripe in the fall in well-drained soil—a very variable plant both in size and the number of branches produced. Several subspecies are recognized. The best forms for food production are bushy plants up to 16 inches (40 cm) tall with an upright habit that keeps the branches out of the mud.
