FAQ
Frequently Asked Questions
No, it is a common or folk name based on the plant's appearance, not a formal botanical (Latin) name.
It is not recommended for formal academic or scientific writing. Use the specific botanical genus and species name (e.g., Mammillaria spinosissima) if known.
Like most cacti, it requires bright light, well-draining soil, and minimal watering, allowing the soil to dry completely between waterings.
Because its tight clusters of long, slender spines visually resemble the bristles of a brush used for hair.
