Blue Achuma

“Blue Achuma” is a clone characterized by its glaucous, blue-gray to blue-green epidermis. As an “achuma” (a term historically and locally applied to *Trichocereus bridgesii* and related species), it typically exhibits prominent ribs, sparse to moderate spination, and the classic columnar growth habit of the genus.

The precise origin of the “Blue Achuma” clone remains partially speculative. Community member Al Marks indicated that they acquired their specimen directly from Willie Tran. There is speculation within the community, suggested by Dan Hofstad, that the clone may have originated from the nursery Sacred Succulents, though this provenance has not been officially confirmed.

No clone-specific cultivation requirements were detailed in the community discussion. Standard care for glaucous *Trichocereus* species applies: utilize a highly gritty, well-draining soil mix, water deeply only when the substrate is completely dry, and provide strong, filtered sunlight to encourage the development of the characteristic blue glaucous coating.

Analysis of the discussion. The discussion primarily focused on tracing the provenance of the clone and confirming its visual characteristics. Benjamin Schwarzchild (also active as Benjamin Schwarzschild) questioned the lineage and whether it was the same clone, prompting Al Marks to clarify the chain of custody for their specimen, which was sourced from Willie Tran. Dan Hofstad suggested a connection to Sacred Succulents. Lawrence Smith confirmed its status as a representative example of a blue-gray/green achuma.

Lawrence Smith is recognized as a primary expert within the Trichocereus community, and his identification of the clone's physical characteristics is treated with the highest level of confidence. Al Marks is rated highly (8/10) regarding the immediate provenance of his own specimen, as he provided direct, first-hand acquisition details.
