The name of this genus refers to the similarity of the plant with Aztec sculpture designs. The species epithet 'ritteri' has been selected to honor the collector Friedrich Ritter.
Blooming Habits:
The Aztekium blooms throughout the summer. The small pinkish and white flowers are produced abundantly. They generally measure less than 0.4 inch in diameter (1 cm). They are followed by small pink fruit that open when ripe and let out tiny seeds.
