Water: Regular water in spring to autumn allowing soil to dry between waterings, keep dry in winter.

Flower: Yellow, often failing to open except on really hot sunny afternoons.

Min temp: Best kept frost free but will take a slight frost for short periods.

Cultivation: As with all Frailea it remains small and is an ideal plant where space is at a premium.

Plants are short lived normally 10 to 15 years.
