Torch Azalea (Rhododendron kaempferi) - Description
This Azalea's genetic origins are traced to Korea and Japan, and was the result of the extensive work of Holland breeders and nursery men. They form nice open branched shrubs that are semi-evergreen. In midseason these Azaleas explode with large flower trusses of bright red blooms. By the fall they develop a pleasing reddish color to the foliage that should last all winter. Grow this in well drained acidic soil that is amended with lots of organic matter and in some partial shade and you will be rewarded for your efforts by this hardy azalea!
