The Japanese azaleas and our native azaleas have been in flower (and some are past) for awhile, but the evergreen
Rhododendrons are later. Ours are just starting to flower. In my part of the world, in the SE US, we have lovely native evergreen rhododendrons in the mountains, but the ones that do best here in the foothills and Piedmont have a bit of hybrid vigor, thanks to some Asian genes and happy crosses. But still, they're fussy about site; the ones that have flourished have light morning sun and are protected from harsh summer afternoons. Perfect drainage helps protect against
Phytophora spp. (which cause root rot).
