Here's a roof patio in Pacific Heights a year after I planted it. It is a southern facing patio that can really bake on those sunny days. In the top photo from the upper left: Phormium, Chamaerops h. cerifera, Lotus berthelotti and Philodendron xanadu.
In the next photo from the left: Cordyline soledad with Lotus berthelotti, Podocarpus gracilior, Cussonia transvaalensis again with Lotus. And the last photo is a Cycad with an amazing fern I got at Flora Grubb Gardens but can't remember the name.
