It is tough to beat Formosa Azalea flowers for their colorful appearance, shape, or as a draw for hummingbirds. The pinkish-lavender flowers open in spring, revealing a darker center of color. The showy color display rises above deep green and delicate leaves. Formosa azaleas grow to a height of 6–8' and a spread of 4–6' at maturity. This shrub grows at a slow rate, with height increases of less than 12" per year. It's important to fertilize Azaleas each spring with a good evergreen fertilizer (if evergreen variety). We recommend using Fertilome Azalea/Evergreen Systemic Fertilizer immediately following flowering season. Full sun and partial shade are best for this shrub, meaning it prefers a minimum of 4 hours of direct, unfiltered sunlight each day. Formosa azaleas prefer acidic, moist, well-drained soil but tolerates periodic dry soil once established. *Item not available for shipping. In-store pick up only.
