Common name: Crimson Crown cactus. Scientific synonyms: Echinopsis deminuta, Echinocactus deminutus, Aylostera deminuta. This species is native to Tucuman, Argentina.

They are dark green cacti with a globular body that reach 6 cm (2.36") in height and form tight colonies. They have up to 13 ribs with gray areolas and 10-12 radial spines. The abundant and showy red flowers measuring 3 cm (1.18") in diameter usually cover the cactus in spring. They can bloom even when they are very young.

They are used in pots and planters for balconies, windows, greenhouses or very illuminated interiors.

Rebutia deminuta grows in direct sunlight or semi-shade exposures. They resist high temperatures well but not cold below 3 ºC (37.4 ºF).

The soil can be a mixture of 75% leaf mulch and 25% coarse siliceous sand.

Water moderately at the rate of once every 15 days in spring, once a week in summer, once every 20-25 in autumn and do not water in winter.

Fertilize once in spring with mineral fertilizer for cacti and succulents.

They do not need pruning.

They are sensitive plants to excess humidity. Indoors, they should be located in a well-ventilated place to avoid mealybugs.

They are propagated by separating suckers or from seeds sown in the nursery in spring.
