Frankeniaceae
Frankeniaceae is a family of flowering plants in the order Caryophyllales, often referred to collectively as the sea heath family. These plants are typically small, perennial subshrubs or herbs that have evolved highly specialized mechanisms to thrive in saline and arid environments where other vegetation fails.

Frankeniaceae
The distribution of this family is global, primarily concentrated in arid and semi-arid regions of both hemispheres. They are frequently found in salt marshes, alkaline deserts, and coastal areas of Australia, Africa, North and South America, and the Mediterranean basin, which highlights their remarkable adaptation to harsh environmental conditions.
Botanically, Frankeniaceae are characterized by opposite, often revolute leaves that are frequently covered in salt-secreting glands. The flowers are generally small, hermaphroditic, and possess a persistent tubular calyx. These features allow the plants to maintain water balance despite high osmotic pressure caused by soil salinity.
Cultivation of Frankeniaceae requires specific environmental conditions, primarily high solar radiation and well-draining, saline-rich substrates. They are not considered traditional field crops but are managed in ecological projects. The key to their survival is maintaining the correct balance of soil minerals, as they are obligate halophytes.
The primary economic use for this family is in ecological restoration and landscape architecture, particularly for stabilizing soils in coastal or inland saline areas. They serve as valuable genetic resources for breeding crops with improved salt tolerance, which is increasingly relevant in the context of global soil salinization.
