I see you already have tall sedums, I would add some more of them.
There are kinds like Frosty Morn which is variegated, and Matrona which has burgundy tinted leaves.
Another tall sedum which is VERY dark burgundy is Sedum 'Postman's Pride'.
Then there is one that is so dark purple it looks black: Sedum 'Purple Emperor'.
And you can add some grasses like Blue Oat Grass which likes fast draining soil...aka Helictotrichon sempervirens.
Not invasive like some grasses either.
Then all around all of the above plants, use groundcover sedums, and a good charteuse (limey-yellow) one is Sedum Angelina.
And it's evergreen, and winter colors are flushed with hot orange. It has a blue colored cousin called Blue Spruce sedum, also evergreen low groundcover, aka Sedum reflexum. Another good one is the Graveyard Sedum' aka Sedum sarmentosum. This will be a pale lime green in stressed out conditions too. Sometimes is will even look yellow in really poor soils.
You can interplant all the groundcover sedums with larger varieties of Sempervivums, especially using the varieties that contrast with burgundy and blue tones. And you can stick in a variegated Yucca such as Color Guard which would be a spikey sea urchin looking accent with GREAT evergreen foliage. Loves hot, dry full sun conditions.
OK...I am all typed out now, on vacation in Newport, RI on my hubby's laptop...which I can not stand the little keyboard.
Plus he is pouting cuz I am neglecting him on his birthday.
One more suggestion, plant something along the chain link fence, evergreens, maybe some Rhodies spaced with some Hollies(at least 3-4 plants per group), and maybe a few Dwarf Alberta Spruces...the fence really has to be hidden somehow.
