|The Satsuki hybrids are hardy to 5 degrees Fahrenheit. Their compact form and neat appearance has made them a favorite for the smaller garden, bonsai work or as a foreground grouping. The large flowers start late in the season. Popular cultivars include 'Bunkwa' a blush pink, 'Flame Creeper' an orange red, 'Gumpo' a white, 'Gumpo Pink' a rosey pink, 'Hi Gasa' bright pink, 'Macrantha Pink' bright pink, 'Macrantha Red' a salmon red, 'Roseaeflora' rose pink, 'Shinnyo-No-Tsuki' violet red with a white center, and 'Wakebisu' salmon pink. Technically, azaleas fall into the genus Rhododendron though they have long been refered to by the genus Azalea. Similar characteristics include leaves which are evergreen and smaller than most rhododendron, spring flowers that are trumpet-shaped and white, pink, red, or purple. Form is dense and rounded regardless of height. All azaleas love well-drained, acid soil and should be planted high preferably on raised beds. Partial shade is preferable too. It is arguable that azaleas produce more flowers in full sun, but maintenace and water requirements become important issues then. Prune immediately after flowering has finished. Begin by removing only dead or weak wood, then shape if needed. Though azaleas have a potentially large list of possible pest and disease problems, they are usually trouble free if planted correctly in proper cultural conditions.
