Abstract

A new and distinct Rhododendron hybrid plant used as a rootstock or flowering shrub that exhibits hardy and vigorous growth.

Description

Botanical classification: Rhododendron hybrid.
Varietal denomination: ‘Rhodunter 48’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Rhododendron hybrid used as a flowering shrub or rootstock known by the varietal name ‘Rhodunter 48’. The new variety was discovered in Ahrensburg, Germany. The new variety is the result of a planned breeding program between an unpatented and unnamed plant of Rhododendron fortunei (female parent)×cv. ‘Cunningham's White’ (unpatented male parent). The new variety exhibits matroclinal morphological features. ‘Rhodunter 48’ exhibits distinct but similar leaf venation to both parents, as well as similarities in color and shape. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.
DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawings illustrate the new cultivar, with the color being as nearly true as is possible with color illustrations of this type.
FIG. 1 shows a close-up view of the flowers of the new variety; and
FIG. 2 shows the new variety grown to a flowering plant.
 DESCRIPTION OF THE PLANT
The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions performed using tissue culture medium for shoot multiplication of Rhododendron species and which were carried out in Ahrensburg, Germany. The color readings were taken in natural daylight. The field-grown plants were five years old when described (unless indicated otherwise). The soil was a sandy loam mixed with peat. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
