Epithelantha micromeris cristata, commonly referred to as the “Button Cactus Crested Form,” is a rare and fascinating variety of the Epithelantha genus. Native to northern Mexico and parts of the southwestern United States, this plant is highly sought after for its crested growth, which forms intricate, fan-like shapes.
The cactus is adorned with fine, silvery-white spines that give it a frosted appearance. These spines densely cover the plant, providing protection from harsh sunlight and adding to its charm. The crested form of Epithelantha micromeris is highly valued among collectors for its unusual and compact growth habit. Unlike the standard cylindrical or spherical shapes, the crests create an undulating, sculptural effect that makes each specimen unique.
During the growing season, typically spring to summer, this cactus may produce small, pinkish flowers, which are followed by tiny red fruits. The fruits add a splash of color and contrast beautifully with the cactus’s silvery tones.
How to Care
- Light: Thrives in bright, indirect light. Direct sunlight should be filtered to avoid scorching the delicate spines.
- Watering: Water sparingly, allowing the soil to dry completely between waterings. Overwatering should be avoided as it can lead to root rot.
- Soil: Prefers a well-draining cactus mix with added pumice or grit to mimic its native rocky habitat.
- Temperature: Keep in temperatures between 20°C and 30°C (68°F to 86°F). Protect from frost and extreme cold.
- Fertilizer: Use a diluted cactus fertilizer during the growing season, but sparingly, as this cactus requires minimal nutrients.
- Repotting: Repot only when necessary, as this plant prefers to remain slightly root-bound. Handle with care to avoid damaging the crest.
- Propagation: Propagation is challenging and usually done by grafting due to its unique growth form.
