Rhododendron relative capable of thriving in dry soil (6)

I believe the answer is:

azalea

(Other definitions for azalea that I've seen before include "Garden plant related to rhododendrons" , "Type of rhododendron" , "Flowering shrub akin to rhododendron" , "Rhododendron relative" , "Rhododendron subgenus" .)

I've seen this clue in the Sydney Morning Herald.
