The Fields Cactus and Succulent Garden was created by Ralph Fields. Ralph obtained many live cacti plants by purchasing a share in field expedition in the Americas, undertaken by Harold Blossfeld, another German botanist. Several plants from The Fields Garden have been donated to the Royal Botanic Gardens Victoria Melbourne Gardens, where many Trichocereus from the Fields collection can be enjoyed in the Arid Garden section.

Dawson’s Cactus Garden was created by Tom Dawson and Justin Gill in Bendigo during 1933. Hosting over 2000 species during its peak, The Dawson Garden was Australia’s largest cactus nursery for over a quarter of a century. The Dawson Garden was purchased by new owners and renamed as Bendigo Cactus Garden in 1992.

Damascus creator Paul purchased seed from the Herbalistics Nursery and another unknown source ~2007. These seeds have grown into what appears to presently Australia’s largest San Pedro collection when measured by sheer mass of plant material.

The Urban Tribes Garden creator Mark Camo began propagating San Pedro in 1991, following a visit to South America and time in a small village located a two days’ walk from Tacna. A shaman from this village gifted the Urban Tribes founder three of their favourite San Pedro clones, which have been propagated ever since. The village shaman also shared San Pedro seeds from their favourite plants.

Shaman Australis Botanicals was established in 1998 by Torsten Wiedemann to distribute rare ethnobotanical plants. Cacti were part of this collection from the beginning. While many clones were named by Torsten, he has also become guardian and source of many more clones from collectors who have since stopped sharing. Torsten also runs The Corroboree forums, where many clones were initially traded and named, many named after SAB forum members.

Herbalistics was founded in Billinudgel, NSW in 2003 by Darren Williams, later relocating to Bli Bli, QLD. A nursery and seed company growing many psychoactive, bushfood and plants of ethnobotanical interest, Herbalistics has always had a focus on breeding and selection of Trichocereus and Echinopsis for multiplication. Having grown 10's of thousands of Trichocereus and Echinopsis from seed, Darren selected some of the interesting ones and gave them the HB numbers below.

Will M started collecting cactus 14 years ago when he was gifted a T. pachanoi “PC” and a T. bridgesii “Bruce” cutting at a meet up for the Corroboree forum. The cactus bug bit hard and Will spent his free hours learning about the many different San Pedro clones available in Australia, attempting to catch them all. Over the years his obsession changed and grew from getting every T. bridgesii available, to getting some international clones, to producing coloured flower crosses.

Mark Hoffman started growing Trichocereus in 2012. Mark’s collection focuses on sacred cactus with a history of ethnobotanical use.

Fahim is a prolific sharer of cacti culture and a regular host of much loved ‘grafternoon’ parties. Fahim is a master grafter with a particular taste for T. terscheckii and habitat clones.

A little like a cordyceps fungus taking control of an ant for the continuation of that species, Trichocereus took over Gus Freeman around 12 years ago. Gus now grows, cares for, propagates and spread their seeds with glee and a feeling of purpose, if not complete control. The goals of Gus’ garden is to appreciate these plant’s beauty and watch them grow and change, as well as create new plants for other people that are exciting and hopefully different to the norm.

When creating seeds, Gus tries to focus on making hybrids that have a high likelihood to eventuate in interesting plants, especially reliably monstrose and crested, coloured flower hybrids mixed with taller plants, and fatties mixed with others to create new and interesting phenotypes. Gus has a strong desire to create tall, ‘san pedro’ looking plants that also have a coloured flower. This is a long-term goal that is currently a work in progress. To truly achieve this will require generations of breeding. This will hopefully result in some of Gus’ named clones being spread to many other gardens as feature plants in the future.

Micromegas' garden started with a single T. pachanoi "PC" plant in a bathtub, but after realising the importance of plants to life in general and several trips to the Americas to get to know Cactaceae up close and personal, has expanded to cover five-to-ten acres of mixed planting and an ever-expanding Trichocereus tribe.
