Synonym is Neoporteria occulta. The plant is origin from Northen Chile. It i particular for unusual colour of body : from pale pinkish-grey to black. It is a summer-growing species. I use too mineral soil and watering regularly from May to September and no-water in winter. I prefer to have about +10°C in winter and no full sun in summer. In Italy often summer is too hot and dry and that’s no good for Neoporteria. Slow-growing plant. Last summer was fresh and my happy plant gives me a lot of flowers. I prefer watering using rain water.
