Propably here are growers with a similar taste....
At the moment the shown clones are in a small number in stock, so they aren`t commercial available at the moment and so no name is given.
here are some further clones
a dark selection of Dact. aristata
my darkest selection of Dact. foliosa x elata, from 2010 first flowering plants
a nice, dwarf selection of Dact. foliosa x elata
Dact. fuchsii selection
