Variety traits

Rhododendron doubleness

Rhododendron L.

Doubleness in rhododendrons is a genetically determined ornamental floral trait characterized by an increased number of petals due to the formation of double or triple corollas.

In the reference 38 varieties crop Azalea, where this is mentioned in the description.

The trait of doubleness in rhododendrons, including deciduous azaleas and semi-evergreen forms, is a varietal characteristic and is unrelated to pathological conditions. Viral reversion, known in other crops by the same name, is not characteristic of rhododendrons.

In breeding, this phenomenon is valued as an aesthetic merit that creates the effect of a full inflorescence. There are no standardized methods for quantifying this trait, and the presence of doubleness does not require any adjustments to standard rhododendron cultivation practices.

General information about the subject — on the page Double flowering / Reversion.
