Latin name of the genus and species: Medinilla magnifica.
Variety denomination: ‘ROYAL TWIST’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct hybrid cultivar of Medinilla plant, botanically known as Medinilla magnifica, hereinafter referred to by the cultivar name ‘ROYAL TWIST’. The genus of Medinilla belongs to the Melastomataceae family.
The new Medinilla ‘ROYAL TWIST’ is a product of a planned breeding program conducted by the inventors, Elly Black and Nico D. M. Steur, in Assendelft, The Netherlands. The seed parent is the Medinilla selection designated ‘82347005’ (unpatented). The pollen parent is the Medinilla selection designated ‘82341131’ (unpatented). The objective of the breeding program was to produce a new Medinilla variety with a good growing habit and an attractive inflorescence. The crossing was made in 2008.
‘ROYAL TWIST’ was discovered and selected by the inventors in 2010, as a single flowering plant, at a research greenhouse in Assendelft, The Netherlands.
Asexual reproduction of the new Medinilla magnifica ‘ROYAL TWIST’ by vegetative means by terminal shoots was first performed in 2013 Assenfeldt, the Netherlands. Subsequent propagation has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true-to-type.
BRIEF DESCRIPTION OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘ROYAL TWIST’ which in combination distinguish this Medinilla magnifica as a new and distinct cultivar:
- 1. Solid growth habit; plants are sturdy and not leggy.
- 2. Erect plant, measuring about 35 cm in height (above the pot when first flowering);
- 3. Glossy green colored leaves, measuring about 16 cm in length.
- 4. Pendulous panicles with red-purple (RHS 64C) colored flowers.
COMPARISON TO PARENT PLANTS
The female and male parents are no longer available for comparison.
COMMERCIAL COMPARISON
Of the commercial cultivars known to the present inventors, the most similar in comparison to the new Medinilla ‘ROYAL TWIST’ is the Medinilla ‘DOLCE VITA’ , unpatented. Plants of the new Medinilla ‘ROYAL TWIST’ differ from plants of Medinilla ‘DOLCE VITA’ in the following ways:
- 1. Plants of ‘ROYAL TWIST’ are larger than ‘DOLCE VITA’.
- 2. Plants of ‘ROYAL TWIST’ are taller than ‘DOLCE VITA’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Medinilla ‘ROYAL TWIST’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describes the color of ‘ROYAL TWIST’.

DETAILED BOTANICAL DESCRIPTION
‘ROYAL TWIST’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, day length, fertilizers and humidity without any change in the genotype of the plant.
The aforementioned photograph, together with the following observations, measurements and values describe the new Medinilla ‘ROYAL TWIST’ as grown in a greenhouse in Assendelft, the Netherlands, under conditions which closely approximate those generally used in a commercial practice.
Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001 Edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions in a greenhouse in Assendelft, The Netherlands. The age of the plants of ‘ROYAL TWIST’ described is about 50 weeks from potting.
