Rebutia krainziana var. inermis (syn. Rebutia pygmaea) - Mature Specimen

Rebutia krainziana var. inermis, also known under the synonym Rebutia pygmaea, is a distinctive clustering cactus valued for its unusual almost spineless appearance and heavily textured tuberculate stems. Unlike the more common smaller offsets often seen in cultivation, these are mature established specimens with significant age and character.

Older plants gradually develop swollen corked bases and dense clusters of rounded heads, creating highly sculptural forms rarely seen in standard production material.

Care

• Light: Bright filtered light to morning sun.

• Temperature: Cool to intermediate growing conditions.
• Media: Very free-draining cactus or mineral-based mix.

• Dormancy: Keep drier during cooler months.
