Eryngium ebracteatum, the burnet-flowered sea holly, is a mostly spineless evergreen perennial from damp South and Central American grasslands, grown for its deep-red cone-shaped flower heads. Full sun and well-drained soil matter most, since it rots in cold, waterlogged conditions despite its wet-meadow origin.
Eryngium ebracteatum Lam., the burnet-flowered sea holly, is a herbaceous perennial native to damp grasslands in South America. The species is occasionally cultivated as an ornamental plant.
The most frequently cultivated species of the genus Eryngium are in the subgenus Eryngium (native to rocky and coastal areas). The New World grassland species are cultivated less often but are gaining popularity due to their fit within the naturalistic planting movement. In cultivation, Eryngium ebracteatum requires full sun and moderately fertile soil. Despite being native to wet areas, it is prone to root and crown rot if it receives a combination of low temperatures and waterlogged soil. Most specimens of Eryngium ebracteatum cultivated are of the variety 'poterioides'.
Eryngium ebracteatum is widely distributed in South and Central America, including Brazil, Costa Rica, Paraguay, Uruguay and Venezuela. It is native to undegraded frequently flooding pampas as well as humid mesophytic meadows, the species is found at elevations of 130 to 1600 meters.
