About Rhododendron
Rhododendron intermedium, also known as the intermediate rhododendron, is a natural evergreen hybrid celebrated for its abundant and showy bloom.

Care tips
It prefers indirect light or partial shade, avoiding direct strong afternoon sun which can scorch its leaves. Consistent watering is required to keep the substrate moist but not waterlogged, especially during flowering and dry periods. Use an acidic, well-draining substrate rich in organic matter, specifically formulated for ericaceous plants or acid-loving species. A common mistake is planting it in alkaline soils, which leads to chlorosis and poor development.
