A small growing cactus with fleeting white flowers that open at night. The Llifle Encyclopedia of Cacti says: "This tiny plant seems much underrated in cultivation, perhaps because it so easy to grow, notwithstanding this, it is one of the most fascinating and showy species! Eastern Argentina ( Santiago del Estero, Santa Fe, San Juan, San Luis, Mendoza, La Rioja, Mendoza, Colonia Ceres). Echinopsis mirabilis has a relatively wide range, is known from at least four disjunct areas, the species is not particularly abundant but is common. The species grows on the edges of salinas and in monte shrublands, often under shrubs in flat prairies up to the base of mountains. There are no known major threats for this species. This cactus is cultivated for its flowers and is among the easiest species to grow, flower and propagate. Indicated for full sun or half shade exposure, water regularly from march to October, rot prone in winter, needs good drainage. It needs to be kept in a cool place during winter rest (can briefly tolerate temp. as low as -4°C) Stems may possibly become purple and limp in winter but revitalize in early spring. Occasionally the plants reach some 15cm tall, but this seems rare. The plants seem to die long before this, and are best replaced with fresh seed-raised ones." |
