Sulcorebutia minima

This species is a dedicated summer grower, syncing its growth with the heavy precipitation and storms that move across the Bolivian Andes during the warm months. It kicks off its active season in mid-to-late spring by producing rings of brilliant, oversized magenta-red flowers directly from the base of the stems. It enters a strict, dormant winter rest as the habitat turns bone-dry and temperatures drop near freezing. In cultivation, its taproot is exceptionally prone to rot from stagnant moisture; it demands an inorganic, coarse mineral substrate (like an 80% pumice and granite mix) and should be watered thoroughly but only when completely dry during summer, tapering off to absolute dryness over winter to trigger the next spring bloom cycle.
