This plant is so small that when grown alone it is quite inconspicuous, but de Laet has grown it very successfully as a graft on one of the cylindric cacti. When grown this way it gives off many new plants, forming a cespitose mass and flowering freely. De Laet also lists in his Catalogue the variety cristatus under Echinocactus minusculus.
