Variety traits

Rhododendron flower color

Rhododendron L.

This trait is a key ornamental parameter for Rhododendron, evaluated qualitatively through visual characteristics, color saturation and purity, or quantitatively using CIELAB color models.

In the reference 15 varieties crop Azalea, where this is mentioned in the description.

Color evaluation is carried out at the full bloom stage, taking into account the tendency of petals to fade in the sun and changes in color intensity during flower development. In breeding, the concepts of saturation and tone purity are used, and the color palette covers a wide spectrum from white and yellow to purple, including the presence of characteristic spots or blotches on the petals.

The color intensity of Rhododendrons depends directly on light conditions: many varieties require diffused light to prevent pigment fading. Furthermore, color can act as an indicator of plant health, as atypical paling or the appearance of spots often points to an imbalance in soil acidity, nutrient deficiencies, or fungal infections such as gray mold.
