Swaps
Most of what I grow is done on a very small scale, but I am always prepared to swap cuttings and seedlings. The amount of material I have available at any one time is usually related to how well my various plants of the Opuntia family have been growing as most of the propagation I do at the moment is vegetative.
In the spring I will compile a list of these plants available for swap on this site, but I don’t expect it to contain more than a handful of species to start with.
