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

How to Grow and Care

Tecticornia pergranulata is also part of a separate group called the Glassworts. It is a halophyte, which means that it grows in areas with a high content of salt in the soil. It can be found along the coasts and in the salt marshes and mangroves. Glasswort quickly colonizes mudflats in salty marshes, where other plants cannot survive. People cultivate these plants as a source of food, oil, and fuel.

This plant prefers a rich organic soil with ample nitrogen and regular watering. It is not known if the plant will require periodic inundation by salty water to grow well. Glasswort is difficult to grow in cultivation, it can succeed in gardens if sown as soon as the seed is ripe in the autumn in a well-drained soil… – See more at: How to Grow and Care for Glasswort
