A small sampling of some of the plants I have found to be heat-hardy in Phoenix.  

 

Blue Potato Bush {Lycianthes rantonnetii}

 

Plumbago auriculata

 

Cissus capensis

 

Coral Fountain {Russelia equisetiformis}

 

 Haworthia attenuata-fasciata

All of these except the Russelia require at least 50% shade from the death star.

Hi stranger! What a nice surprise to see your post pop up in my Feedly :-) I have Plumbago which is very happy in the almost total shade of one side of my house. The Leaf Cutter Bees are happy it's there! I also have Haworthia but much smaller than yours. I have hope :-)

I've been away from blogging since I discovered Instagram where I've been sharing daily photos of garden and desert stuff. Love that platform. I do intend to come back to blogging, though. (instagram.com/ezpixels)

Hope all is going well!

Marianne!

My Hawarthia has doubled in size every year. It's been reliable and reassuring to grow.
