Ariocarpus confusus (Star Rock, Living Rock) - 10 seeds

Ariocarpus confusus is a peculiar local form somewhat intermediate between Ariocarpus retusus and Ariocarpus trigonus. These two taxa intergrade in the area adjacent to Aramberri (a natural hybrid?). The peculiarity of Ariocarpus confusus is that it usually develops deep magenta flowers (a color not found in any other populations of A. retusus/trigonus). However, white or pink flowers or variations of the two or even bicolored flowers in the same plant are not uncommon.

HOW TO GROW?

This species is slow growing if compared with other retusus forms, but of easy culture in a well-drained non-organic free-draining soil compost, with ample water during the growing season. The use of a weak low-nitrogen fertilizer during the growing season can encourage growth. The main threat to their development is root rot. Ariocarpus should be kept dry whenever there is a threat of cold. The appearance of Ariocarpus can benefit greatly by watering the plants from the bottom. This practice will help keep the “wool” on the plant's top from becoming matted or discolored. Need light shade to full sun. Frost Tolerance: Hardy to -10°.
