I did not realize Campomanesias were so popular a few years ago. I wonder if that was just in Australia or with rare fruit growers here in the US, as well. I rarely see anyone mentioning Campomanesias, much less selling plants or seeds. Those plants people bought a decade ago must have died or been replaced by something else, otherwise I would think at least some of those collectors would be offering seeds for sale.
Out of curiosity, which two species did you believe were worth collecting, and what were their flavors like?
