Juvenile leaves of Rhododendron hybrid plants sometimes show strikingly bright red or orange colors. Red pigments, anthocyanins can appear on the leaves at specific developmental stages and may be induced by various stress factors. The phenotype is not usually seen when the plants get older. However, red colors can be made more permanent by extensive breeding. A good example of this is 'Ever Red', an astonishing introduction from Glendoick Gardens.
In the picture gallery of this page I'll show some examples of my juvenile plants with red or orange new growth.
