Acanthocalycium thionanthum SEEDS

Acanthocalycium thionanthum seeds grow into the sulphur-flowered spiny-calyxed cactus — a globose to short-columnar cactus native to the desert and dry shrubland biome of north-western Argentina. The genus Acanthocalycium means 'spiny-calyxed' (from Greek akantha = spine + kalyx = calyx). The epithet thionanthum means 'sulphur-flowered' (from Greek theion = sulphur + anthos = flower), referring to the pale yellow, sulphur-coloured flowers. Produces globose, ribbed, spiny bodies with pale yellow to white flowers. Three subspecies are recognised: subsp. thionanthum, subsp. glaucum (Catamarca) and subsp. ferrarii. Cold-tolerant. Family Cactaceae.
