Fun Facts
- 🌱 Dwarf azaleas are actually a group of cultivars of Rhododendron species, and the genus Rhododendron contains both azaleas and rhododendrons—azaleas are simply rhododendrons with specific characteristics like more delicate flowers and typically deciduous foliage.
- 🌱 Some dwarf azalea varieties were bred in Belgium and Japan and have been cultivated for over a century; Japanese azaleas in particular have been refined through selective breeding for over 300 years.
- 🌱 Azaleas require acidic soil because they have a symbiotic relationship with mycorrhizal fungi that help them absorb nutrients in acidic conditions; this is why they rarely thrive in alkaline soils regardless of other care.
