RE: Summer color for shade,and other challenges

We also lost a Hardenbergia this spring, in northern San Diego County.  When I dug it up this morning, I discovered root rot.  Since the plant was in an area that got almost no irrigation since last November, I am tempted to blame the nearly double normal rainfall over last winter.  We had several late spring showers, after the soil started to warm up.

Hi All,
I have a woodsy corner of the garden beneath olives, and was wondering if there are any good flowers for summer color. 
I have a dwarf pomegranate right next to the patio that creates a splash of vermilion,and a clump of red Heuchera 'Santa Ana Cardinal' on another side of the patio, but for the middle ground and background I'm looking for cooler colors.

 Are there any gentians that do well in southern California?  Maybe a purple penstemon that prefers part shade?

Also, I have several large Hardenbergia violacea vines trained on a masonry wall in full sun.  They back a border of roses, euphorbias, lavenders and statice, all of which are doing fine.  This spring, however, I lost about 1/4th of the hardenbergia, and another quarter looks half tan, half green.  Everything else in the border looks terrific.  Any ideas?

Thanks,
