USPP21301P2 - Centradenia plant named ‘Blushing Cascade’ - Google Patents

Abstract

A new and distinct cultivar of Centradenia plant named ‘BLUSHING CASCADE’ that is characterized by light-pink flowers and diminutive red buds, long bloom period, and green foliage infused with red highlights. In combination these traits set ‘BLUSHING CASCADE’ apart from all other existing varieties of Centradenia known to the inventor.

Description

Genus: Centradenia.

Species: inaequilateralis.

Denomination: ‘BLUSHING CASCADE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Centradenia grown as an ornamental perennial for use in containers and hanging baskets, and as a shrub for the garden and landscape. The new invention from the family Melastomataceae is known botanically as Centradenia inaequilateralis and will be referred to hereinafter by the cultivar name ‘BLUSHING CASCADE’.

‘BLUSHING CASCADE’ was discovered in 1998 as a naturally occurring branch sport found growing on a single plant of Centradenia ‘Cascade’ (unpatented). The sport parent, ‘Cascade’, was growing in the inventor's nursery in Petersfield, Hampshire, United Kingdom. The inventor observed that the sported branch bore light pink flowers whereas the flowers of ‘Cascade’ are red-purple in color. The inventor made softwood cuttings from the sporting branch and established such asexually reproduced plants on their own roots. Once the inventor was able to observe fully grown whole plants of ‘BLUSHING CASCADE’ the inventor concluded that ‘BLUSHING CASCADE’ also exhibited brighter colored foliage, a stronger plant habit and a longer flowering season when compared with the parent ‘Cascade’. The inventor is not aware of any other varieties of Centradenia that resemble ‘BLUSHING CASCADE’ other than the parent variety, ‘Cascade’.

The first asexual propagation of ‘BLUSHING CASCADE’ was conducted by the inventor in Hampshire, United Kingdom. Asexual propagation was accomplished in 1998 at the inventor's nursery. The method used was softwood cuttings. Since that time under careful observation ‘BLUSHING CASCADE’ has been determined fixed, stable, uniform, and to reproduce true to type in subsequent generations of asexual propagation.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Centradenia cultivar named ‘BLUSHING CASCADE’. These traits in combination set ‘BLUSHING CASCADE’ apart from all other existing varieties of Centradenia known to the inventor. ‘BLUSHING CASCADE’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions without however any variance in genotype.

• • 1. ‘BLUSHING CASCADE’ bears a large number of light-pink flowers. During bloom period, diminutive red buds are present, the combination of which creates a pronounced ornamental effect.
  • 2. ‘BLUSHING CASCADE’ exhibits a long flowering season, winter through spring in frost-free zones.
  • 3. ‘BLUSHING CASCADE’ exhibits compact habit.
  • 4. ‘BLUSHING CASCADE’ exhibits red stems.
  • 5. ‘BLUSHING CASCADE’ exhibits green foliage infused with red highlights.
  • 6. ‘BLUSHING CASCADE’ reaches 32 cm. in height and 77 cm. in width at maturity.
  • 7. ‘BLUSHING CASCADE’ is hardy at least in USDA Zone 8.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Centradenia cultivar named ‘BLUSHING CASCADE’ showing the color as true as is reasonably possible to obtain in color reproductions of this type. Color in the drawings may differ from color values cited in the detailed botanical description, which accurately describe the actual color of the new variety ‘BLUSHING CASCADE’. Drawings are of plants that are greenhouse grown.

The drawing labeled FIG. 1 illustrates a plant of ‘BLUSHING CASCADE’ growing in an 8 inch container out of doors in Santa Barbara, Calif. The illustrated plant is approximately 15 months of age.

The drawing labeled FIG. 2 illustrates a close-up view of the light pink flowers and diminutive red buds of the plant shown in FIG. 1.

Both drawings were made using conventional techniques and although flower and foliage color may appear different from actual color due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Centradenia cultivar named ‘BLUSHING CASCADE’. Observations, measurements, values and comparisons were collected in Arroyo Grande, Calif., from 18-month-old plants grown out-of-doors in 2-liter containers. Color determinations are made in accordance with the 2001 Royal Horticultural Society Colour Chart from London, England, except where general color terms of ordinary dictionary significance are used. The growing requirements of the new variety ‘BLUSHING CASCADE’ are similar to the species.
