Comments: A good plant for beginners as it is not very demanding. Over many years the plant has been extensively hybridised (mainly with Lobivia) to give many flower colours ranging from white to deep red, yellow, orange, ect. The plant has been so extensively hybridised over the last few years that the original form has become fairly hard to come by. There is also a chlorophyll lacking form called E. chamaecereus var. lutea which is pale yellow and can only survive as a grafted plant. Although this plant has recently been moved to the genus Echinopsis many sellers and growers still prefer to call it Chamaecereus sylvestrii.

Pictured below are the hybrid "michaela" a white flowered form and the grafted yellow bodied E. chamaecereus var. lutea.
