“Thirty years ago, I got RS0001 from the defunct Sticky Business nursery in Sebastopol, California. I got RS0002 when a cactus collector who was moving out of the country gave me his collection, which was mainly peruvianus that he had obtained form various local sources and that looked identical. I got RS0003 from Makuto Kimura's defunct nursery near Gilroy, California. All three varieties looked similar but had a distinct appearance that enabled me to recognize them without using labels. But when cultivated in the same location, they all transformed to look the same, so for the most part I could not tell them apart except for a few that had plant tags. Live and learn. Therefore, when I distribute that variety, which is very likely all one clone anyway or at least siblings form the same batch of seeds, I label it RS0001-3.” -Kakster, Summer 2019

Cuttings of Trichocereus peruvianus RS0001-3 are sometimes available from Cactus Affinity.
