Dylan asked me > Can you not grow the tuberous Talinum species (caffrum, whitei, > angustifolium etc.) in Phoenix? Yes, we can grow Anacampseros, Avonia, Grahamia, Portulaca and Talinum. It's the lewisias that I (and others) have trouble getting through our summers.

All the Portulacaceae I have grown are not only self-fertile, but self-pollinating. A few are greenhouse weeds under some circumstances. I can't speak to Lewisia. Leo Martin Phoenix Arizona USA
