Azalea ( Rhododendron ) 'Purple Formosa' - Southern Indica Family

Overall Description

Purple Formosa Azalea is a larger sized evergreen azalea from the Southern Indica Family. Produces good numbers of 2 1/2" - 3" diameter rich light to medium purple / lavender colored blooms throughout the spring, and known to also produce smaller, shorter, sporadic "spurts" of blooms through the fall season as well. Has a vigorous, more upright growth habit than most of the other Azaleas we grow.....but is oftentimes maintained at a variety of different heights through periodic pruning / trimming. Foliage is evergreen, and very dark green in color when mature - newer growth & leaves is a lighter shade of green, maturing to a darker shade.

Popular uses for Purple Formosa include hedges, colorful accents or borders, and also works very well to help highlight any semi shaded area. Have even seen this variety used as a larger understory planting under the shady canopies of larger shade trees.

Like all Azaleas, Purple Formosa prefers semi shade, and will even do well in planting locations with mostly shade. Shallow, non aggressive root system makes them a great foundation planting choice, and can even be planted closely together for use as a colorful hedge. This fairly shallow root system however, also requires that Azaleas be given regular waterings - be sure that your Azaleas receive water equivalent to about 1" of rainfall each & every week throughout the growing season.

--Fertilization / Feeding :
For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
