Echinopsis
The genus Echinopsis is one of the most diverse and widely cultivated groups of South American cacti, comprising globular, clustering, and columnar species native to Argentina, Bolivia, Peru, Paraguay, Uruguay, Brazil, and Chile. Adapted to environments ranging from arid deserts and rocky mountain slopes to high-elevation grasslands, Echinopsis species are renowned for their remarkable diversity of form and spectacular floral displays. Many species produce enormous fragrant flowers that often open at night and can exceed the size of the plant body itself. Their ease of cultivation, rapid growth, exceptional flower production, and broad range of sizes make Echinopsis among the most popular cacti for collectors, rock gardens, containers, greenhouses, and xeriscape landscapes. From compact flowering species to massive columnar giants, the genus offers some of the most rewarding cacti in cultivation.
