|This Japanese azalea is a hybridization between R. indcum and R. simsii and has a compact, low, spreading to rounded form that is twiggy and dense. Even the leaves are notably smaller, making it the wonderful bonzai plant that it was originally bred to be. Grows 2 to 4 feet tall and wide. Balsaminaeflorum has showy, funnel-shaped flowers that are rose-pink, sterile, with up to 40 petals, and bloom in late spring.
Plant as you would any of the other azaleas: high and in well-drained, acid soil, rich with organic matter. This is a front of the border azalea because of its lower height. Perfect for the smaller garden. Satsukis seem to be able to handle a little more sunlight than most azaleas, but this does not mean "hot" sun. Filtered light is still best.
The Satsuki are often pruned in the the Japanese garden. If this is the look you are trying to obtain, remember, prune immediately after flowering, so you won't cut off any of next years buds. 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.
