Martín Cárdenas Hermosa (November 12, 1899 – February 14, 1973) was a Bolivian botanist. Cárdenas is considered one of the most important botanists in Bolivia’s history. He is responsible for recording some 6,500 species of plants in his native country. The original plant was named by this chap, but it is unknown if the true description is sub. Denudata , as in subspecies Denudata, …spineless ….or the whole word Subdenudata , used by most today.
My plants were chosen in 7 different countries over the last 35 years. I chose young plants that were already lacking spines, especially the usually large upper central spine of each areole.
Surely theres a good mix of genetics to breed back into. I also sold on to others any that had nasty spines.
so i have a great collection of ….spineless Echinopsis.
They are not for sale …but the seeds are.
Last year they made 15,000 seeds, ish!
SedumShack sells fresh seeds at a great price…..in packs of 100, 500 or 1000.
