Aztekium ritteri
Aztekium ritteri

This CITES I species (threatened with extinction in the wild) grows very slowly when cultivated on its own root - often only 1mm in diameter per year.
For its rareness and intersting wrinkled epidermis, its cultivated a lot by collectors.
The difficulty in cultivation is to get it through its fist few years, imagine a plant only growing to a size of 3mm in 3 years. The one pictured here is grafted on a trichocereus stock, letting it grow much quicker. It´s still only 16mm in diameter and will maybe need a few more years before flowering.
