Detailed morphological descriptions regarding rib count, spination, and exact epidermis color remain undocumented in the primary discussion. ===== History & Origin ===== The origin of the "P7" clone points to two distinct possibilities depending on the geographic region: * **Australian Origin:** The clone is highly likely to be one of a series of eight "P" clones (P1 through P8) introduced in Australia by Miguel El Stillmano. * **United States Origin:** There is speculative association linking the name to a *Trichocereus huanucoensis* specimen distributed by the nursery The Succulent Source. ===== Cultivation Notes ===== No specific cultivation requirements were detailed in the community discussion. Standard *Trichocereus* care is recommended: utilize a highly gritty, well-draining soil mix (50% inorganic material such as pumice or perlite), water deeply only when the substrate has dried out completely, and provide bright, filtered sunlight to partial direct sun depending on regional intensity. ===== Community Discussion & Citations ===== //The discussion revolves around identifying the origin of the "P7" designation. While some US collectors associate it with a Huanucoensis clone from The Succulent Source, Australian grower Miguel El Stillmano clarified that he released a series of eight "P" clones in Australia, making it highly probable that Australian specimens of "P7" originate from his garden.// ^ Date ^ Speaker ^ Confidence Score ^ Key Insight/Quote ^ | 2023 (approx) | Miguel El Stillmano | 8 | "if it's in Aus it's probably one of mine there was 8 Ps in total" | ===== Credibility Notes ===== * **Miguel El Stillmano** (8/10): Rated highly as the primary source and originator of the Australian "P" series clones, providing direct confirmation of the naming convention and total number of clones in the series. * **Bobby Thoner** (4/10): Provided a tentative lead regarding a *T. huanucoensis* from The Succulent Source, but used speculative language ("I think", "Maybe not originally") which reduces confidence.
