General Description

This fine clumping cactus for landscaping is equally suited to container cultivation indoors or out. It is native to northern Argentina where plants are widely adaptable to a wide range of exposures. The plant is composed of many stems that originate at the base of the plant which can grow to a very large crown at maturity. These may stand upright or lie procumbent with slightly upturned tips. Each stem, about the diameter of a baseball bat is dark green, averaging 9 to 11 sharp edged ridges which bear areoles. From these rise from one to many central long central spines surrounded by needle fine 10 to 14 radials, often yellow in color. These may interlace when plants grow in drier locations.

This snow-white nocturnal bloomer is truly stunning in full flower. Night flowering, rich fragrance, funnel formed blooms and the location of the stigmas indicates that bats and moths are vital to pollination. Bats may even feed on the stigmas themselves after lapping up a rich nectar reward. Small fruits follow flowering. Slow growth and a tidy form early in life makes this big bloomer a popular plant indoors and on the patio. It is vital to provide very granular soil to assure rapid drainage. Feed often but lightly during the spring and summer growing season, then provide dry conditions over winter.
