This is a brackish species.

Description
The plants are up to 50 cm long, they are not encrusted and therefore green. The axis is to 0.5 -1 mm in diameter. The branchlets are 6-11 in a whorl, each with 6-9 segments. The stem cortex is diplostichous, tylacanthous. The spine cells are normally solitary, occasionally in pairs and usually shorter than the stem diameter. The stipulodes are in two regular rows. The bract cells are 5-7 and the bracteoles are longer than the oogonium. The plant is monoecious. The gametangia are conjoined at the lowest 1-3 branchlet nodes. The oogonium is up to 1.2 mm long. The oospore is black. The antheridia are up to 500-800 m in diameter. Multicellular bulbils are found in the autumn.

Habitat
Chara baltica is a brackish water species, found in salinity between 2- 10 PSU. The species is frequent in the Baltic Sea, and is elsewhere found in coastal lagoons and fiords. It grows on muddy or sandy bottom, from 0.1  4 m depth. C. baltica has both annual and perennial forms, depending on the depth of growth. The annual forms hibernate by bulbils or oospores, while the perennial forms has oospores, swollen nodes Nacktfüssige Zweige or green plants.
