DESCRIPTION OF THE VARIETY

(7) The following detailed description of the new variety is based upon observations taken of plants grown in Anoucho, Tsu-shi, Mie-ken, Japan. Observations of Kuraangel were taken during the 2007 growing season.

(8) In the following description, color references are made to The Royal Horticultural Society (R.H.S.) Colour Chart, except where general terms of ordinary dictionary significance are used. Botanical classification: Rhododendrum hybrid. Principle use: Flowering shrub for potted plant and open-field cultivation. Parentage: The female parent is Wedding Bouquet, and the male parent Purple Splendor. Propagation: The new variety was propagated using tissue cultures from plants potted in greenhouse facilities in Anoucho, Tsu-shi, Mie-ken, Japan.

Plant: Size.At 3 years of age, plants of the new variety commonly exhibit a height of approximately 40-50 cm and a width of 30 cm. Habit.Vigorous and compact. Foliage: Arrangement.Foliage arrangements are pseudoverticillate or false verticillate, appearing whorled or verticillate, but not actually so. Type.Evergreen flowering shrub, simple lanceolate leaves with an obtuse leaf base, oblong body, acute apex, and obtuse margins. The upper surfaces of the leaves appear semi-glossy, and the bottom surfaces of the leaves appear matte. Venation.Leaves have a netted (reticulate) venation pattern. R.H.S. colour chart 150D on the upper surface of the leaves, and R.H.S. colour chart 150C on the bottom surface. Size.Mature leaves growing midway up the stem commonly are approximately 12 cm in length and approximately 3.5 cm in width. Color.R.H.S. colour chart NN137B on the upper surface, and R.H.S. colour chart 143C on the under surface. Petioles: Size.2.0 cm in length, and 3.0 millimeters (mm) in diameter. Texture.Rough with bristles. Color.R.H.S. colour chart 58B. Branches: Size.Mature lateral branches (one-year old wood) are 2.0 m in length and 7.0 mm in diameter. Internode length.Mature lateral branches (one year old wood) have a 1.0 cm internode length. Texture.Mature lateral branches (one year old wood) are rough with bristles. Color.Mature lateral branches (one-year old wood) R.H.S. colour chart 143C. Peduncles: Size.Approximately 3.0 cm in length and 2.5 mm in diameter. Color.R.H.S. colour chart 178B. Petals: Shape.Petals are generally wavy with a connected base and sharply pointed apex. Size.Approximately 8.0 cm in length and 4.0 cm in width. Texture.Both surfaces of the petals are generally smooth. Sepals: None. Flowers: Period.Blooms approximately April 15 in the evening when cultured at Anoucho, Tsu-shi, Mie-ken, Japan. Appearance.Corymb. Arrangement.Spheroidal. Truss shape.Generally a sphere. Truss size.Approximately 15 cm diameter, and approximately 15 cm in height. Corolla per truss.Approximately 12. Corolla shape.Open funnel shape. Corolla size.Approximately 10 cm in length, 10 cm in width, and 7 cm in thickness. Number of lobes.Five lobes per floret. Margin of lobes.Wavy to frilly. Fragrance.None. Calyx size.Approximately 2 millimeters (mm) in length. Flower bud shape.Lacrimoid. Flower bud size.Approximately 4.0 mm in length and 2.5 cm in diameter. Flower bud color.R.H.S. colour chart 75A. Flower color.One color on the surface of the corolla lobe, with the same color on both the upper and lower surfaces. The surfaces of the corolla lobe is light purple (R.H.S. colour chart N75B). Strong, independent spots (R.H.S. colour chart 42A) are present on the throat of the corolla lobe. Reproductive organs: Stamen number.10. Filament length.Approximately 5.0 cm. Filament color.R.H.S. colour chart 155C. Anther shape.Barrel shaped. Anther length.Approximately 2.0 mm. Anther color.R.H.S. colour chart 155A. Pollen amount and color.High pollen count and R.H.S. colour chart 155A. Pistil length.Approximately 4.5 cm. Stigma shape.Captiform. Stigma color.R.H.S. colour chart 159A. Style length.Approximately 4.0 cm. Style color.R.H.S. colour chart 155D. Ovary color.R.H.S. colour chart 178A. Winter hardiness: Has survived winters with temperatures as low as 3 C. in Anoucho, Tsu-shi, Mie-ken, Japan. Disease resistance: During observations to date, the foliage has been disease resistant. Although generally, Rhododendron hybrid plants are prone to root rot disease, which tends to occur in high temperatures, Kuraangel is resistant to root rot because it is resistant to high temperatures. Successive generations: Reproduces true to type in successive generations as set forth above.
