NOTES: It has been said that these species have adapted themselves to flower while still in the juvenile stage. Survival rate for small seedlings is very low, so if the plant flowers sooner in its life span, then there�s more chance of seed dispersal and more chance of seedling survival in habitat.

The Turbi that thinks it�s a Loph!

Turbinicarpus lophophoroides

Cactaceae (Cactus Family)

 

Form: Turbinicarpus lophophoroides is generally a solitary bodied plant, but multi-headed plants or clumps can occur. Its habitat is Las Tablas, San Luis Potosi, M�xico around 800-1150m elevation. Turbinicarpus as a genus is popular with enthusiasts for their small size and are easy to flower. But with an increase in demand, came an increase in illegal poaching. As a result, the whole genus of Turbinicarpus has been placed under Appendix I of CITES. It has a large tuberous taproot that stores a lot of moisture to sustain itself. Dark green to grey/green body. Starting out spherical in shape, it can then take on a conical shape. Short, white spines, approx. 2-5 per areole in a cross like formation, often curved toward the body. Once mature, the apex is covered in a dense white wool. The plant can retract itself into the soil in times of serious heat and drought. Even just a few inches below the soil surface, the temperature can be significantly cooler. This can also occur in cultivation when the plant has not been watered for a long time. It may also turn more grey-green. These are normal occurrences for this plant.

 

Size: Typically growing to around 2-3inches in height and diameter.

 

Flowers/Fruit: The flowers are rather large for this plant, 1.5 to 2inches in diameter. White to pale pink, darkening to a deeper pink in the center. Stamens are yellow and the stigma is white. The fruit are a pale green and sometimes have scales on them.

 

Sun/Water: T. lophophoroides can take full sun in most regions, but care should be taken to protect from the intense afternoon Southwest USA heat and sun (Arizona, Nevada, California) Light watering during the growing season is all that is needed. Make sure to use a well draining soil mix and that it drys out completely between waterings. A little gypsum can be added to the soil mix. This specie can handle cold temps down to 45-50F if kept dry.

 

Propagation: From offsets or seed. They don�t offset very often, so seed raising is much more common. Relatively easily grown from seed, but they can be slow. They also don�t really like transplanting too much. Care should be taken when repotting this specie.

 

Books/Websites: The Genus Turbinicarpus in San Luis, Potosi is a great reference book. As well as Ariocarpus et cetera � the special, smaller genera of Mexican cacti. Available through Rainbow Gardens Bookshop. A duo of informative websites: Turbinicarpus Information Exchange and Turbinicarpus Species All kinds of great Turbi info! More websites can be found on our Reference Links page.
