Echinopsis aurea subsp. shaferi f. monstrosa ‘Enigma’ (WA Prohibited)

Echinopsis schaeferi ‘Enigma’ Montrose is a compact monstrose mutation forming tight clusters of irregular, knobbly growth. Unlike the standard ribbed species, this clone develops sculptural, unpredictable forms while retaining the species’ bright yellow flowers when mature.

Previously circulated under Trichocereus schaeferi and occasionally mislabelled in cultivation.
