In April-may the plant blooms, producing beautiful, huge flowers: they are up to 12 cm long, almost covering the stems, pink or magenta.


-E. pentalophus is a very easy plant to grow and propagate! It grows fast and blooms easily. Use a very porous standard cactus mix soil, but avoide limestone! Water well in spring-summer, keep it dry in winter. It is rot prone, don’t overwater it. Use pots with good drainage. It is frost tolerant for short period of time. It needs a period of cool rest to produce flowers. Strong light is also necessary for the plant to produce flowers: it likes bright situations inside but also outdoors.
