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.

Some of the newly acquired Lewisia are blooming; I don't know if they
require separate plants for pollination to be successful; but I'll
give it a try anyway.

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.
