Trichocereus macrogonus
There is not a clear line between Trichocereus macrogonus and Trichocereus peruvianus but these are some plants that I received as or I consider to be Trichocereus macrogonus.
From Poot’s House of Cactus, this is in my opinion a Trichocereus macrogonus type plant similar to Trichocereus macrogonus RS0004 and Luther Burbank.
This is not their blue matucana type Trichocereus peruvianus they have growing near their sign.
Cuttings of Poot’s peruvianus #1 aka JS20 are regularly available from Cactus Affinity.
