ivisissa

Ivisissa is a genus of plants in the family Asteraceae, commonly known as sunflowers. The genus contains a single species, Ivisissa helianthoides. This plant is native to South America, specifically found in Argentina and Uruguay. It is an herbaceous perennial that typically grows to a height of 60 to 120 centimeters. The leaves are ovate to lanceolate, with toothed margins. The flower heads are solitary, resembling those of other sunflowers, with yellow ray florets and a dark central disc.

Ivisissa helianthoides prefers well-drained soil and full sun. It is often found in grasslands and open woodlands. While not widely cultivated, it is sometimes used in native plant gardens for its ornamental appeal. The plant reproduces by seeds and also through rhizomes. Its ecological role includes providing a food source for pollinators such as bees and butterflies. Further research into the specific phytochemical composition and traditional uses, if any, of Ivisissa helianthoides is limited in readily available literature. The taxonomy of the genus Ivisissa has been subject to some revision, but currently, it is generally accepted as distinct.
