Hi Phyl!

I think you may be just past the higher end of the spectrum for Rhododendrons, as most sit at a max hardiness zone of 8 (think you may be 9) although there is zone 9 varieties available, you may have to search for them.
If you do decide on them just make sure they have afternoon shade and mulch well as they have shallow roots Smiling

(Some examples are Hydon Dawn, Sun Chariot, True Webster or Blue Diamond)

I'm in zone 9 and we have huge natural wooded parks with thousands of rhodies and nurseries specializing in them.

Here is culture info from the the American Rhododendron Society:

Some quotes:
In hot areas, northern exposures are preferable to southern exposures. Exposure to constant wind is not desirable, especially the salty winds of marine environs. Generally large-leaf rhododendrons are less tolerant of sun and wind than small-leaf rhododendrons or evergreen and deciduous azaleas.

Rhododendrons are acid loving plants. As such they perform best when the soil is acidic (with a pH between 4.5 and 6.0). They need well-draining soil with an abundance of organic matter.

In hot climates, root rot organisms flourish in wet soils and can kill rhododendrons and azaleas. Under these conditions, raised planting beds that incorporate 50% or more fine pine bark can be helpful in suppressing Phytophthora root rot.
