My Turbinicarpus jauernigii
From Northeastern mexico, Turbinicarpus is a genus of 35 species of desert cacti. Turbincarpus grow in gravelly limestone and gypsum soils and in cultivation require a quick draining mineral based mix. Most Turbinicarpus also have a large tap root that anchors them in the loose soil and stores water. In times of drought the tap root can pull the plant nearly flush with the ground making them difficult to find except when flowering.
They are small plants, rarely exceeding 2 inches in diameter. They are also mostly solitary but some species offset occasionally. The spination is generally light, some nearly spineless and some having curly papery spines. The papery spines have the ability to absorb water from infrequent fogs and dews.
Turbinicarpus should be watered moderately throughout the growing season, perhaps every two weeks. They may experience a dormancy period at the hottest times of year and should be watered less at this time. They bloom intermittently at all times of year and the flowers are white, cream, red, pink or yellow. They are mostly propagated from seed.
