Staurogyne is a genus of aquatic plants in the family Acanthaceae. These plants are native to South and Central America, and they are commonly known as star plants.
Staurogyne plants are found in a variety of aquatic habitats, including streams, rivers, and swamps. They have a low, creeping growth habit, with small, pointed leaves arranged in a rosette around the stem. The leaves are typically green, but some species may have reddish or brownish tones. Staurogyne plants produce small, white or purple flowers that bloom above the water surface.
In the aquarium hobby, Staurogyne plants are highly valued for their attractive appearance and their ease of care. They are often used as foreground or midground plants, and their low, compact growth habit makes them ideal for creating a carpeting effect. Staurogyne plants are relatively tolerant of a wide range of water parameters, but they prefer moderate to high light intensity and nutrient-rich water. They can be propagated by stem cuttings, which can be rooted in the substrate or floated on the water surface until they develop roots.
