Rhaphiolepis indica plant named `Creeklin'`

Abstract

A distinctive cultivar of Hawthorne, Rhaphiolepis indica, plant named `Creeklin'`, characterized by its erect, dense, mounded and uniform plant habit; fine plant texture which allows for ease of shearing; small, oblong, mostly flat leaves with an acute apex are initially coppery and mature to a shiny dark green color; dark reddish brown young stem color; and numerous light pink flowers. The combination of light pink flowers with dark brownish red stems, coppery new growth and shiny dark green mature foliage provides the new Hawthorne a striking and unique appearance.

Description

The present invention relates to a new and distinctive cdultivar of Hawthorne plant, botanically known as Rhaphiolepis indica, and hereinafter referred to by the cultivar name `Creeklin'`. It is proposed that the cultivar `Creeklin'` will be marketed under the trade name CandleLight.

The new cultivar was discovered by the inventor in Humble, Tex., as a naturally-occurring mutation of the nonpatented Rhaphiolepis indica cultivar `Harbinger of Spring`, and was observed in a group of plants of the parent cultivar in March, 1992.

Asexual reproduction of the new cultivar by cuttings in Humble, Tex., has shown that the unique features of this new Hawthorne are stable and are reproduced true to type in successive propagations.

The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light and fertility levels, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Creeklin'`:

1. Erect, dense, mounded and uniform plant habit.

2. Fine plant texture which allows for ease of shearing.

3. Desirable plant height which can be maintained at 90 to 120 cm with shearing; unsheared plants will grow to 180 to 240 cm.

4. Small, oblong, flat leaves with an acute apex that are initially coppery and mature to a shiny dark green color.

5. Dark reddish brown young stem color.

6. Numerous light pink flowers.

7. Combination of light pink flowers with dark brownish red stems, coppery new growth and shiny dark green mature foliage provides the new Hawthorne a striking and unique appearance.

The following characteristics differentiate the new Hawthorne from the parent cultivar `Harbinger of Spring` and other Hawthornes commercially known and used in the nursery industry:

1. Plants of the new Hawthorne are denser and more mounding than plants of the cultivar `Harbinger of Spring`. Plants of the cultivar `Harbinger of Spring` have an open plant habit.

2. Plants of the new Hawthorne have a more uniform plant shape than plants of the cultivar `Harbinger of Spring`.

3. Plants of the new Hawthorne are easier to shear and shape than plants of the cultivar `Harbinger of Spring` as plants of the new Hawthorne have a smaller and finer leaf texture than plants of the cultivar `Harbinger of Spring` which have a coarser texture.

4. Plants of the new Hawthorne have leaves that are shorter, narrower and flatter than leaves of plants of the cultivar `Harbinger of Spring`. Additionally, plants of the new Hawthorne have oblong-shaped leaves whereas plants of the cultivar `Harbinger of Spring` have oblanceolate-shaped leaves.

5. Young leaves of the new Hawthorne are coppery and mature to a shiny dark green color, whereas leaves of the cultivar `Harbinger of Spring` have tan-colored young leaves that are dull and paler green at maturity.

6. Young stems of plants of the new Hawthorne are shiny brownish red whereas young stems of plants of the cultivar `Harbinger of Spring` are dull greenish brown in color.

7. Flowers of plants of the new Hawthorne have five petals whereas flowers of plants of the cultivar `Harbinger of Spring` have five to seven petals.

The accompanying colored photographs illustrate the overall appearance and flower color of the new Hawthorne, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photographs on the third sheet are close-up views of typical plants of the cultivars `Creeklin'` (top) and `Harbinger of Spring` (bottom) showing the differences in flower petalage and foliage color. Actual flower and foliage colors may differ from flower and foliage colors in the photographs due to light reflectance.

The following observations, measurements, values, and comparisons describe plants grown in Humble, Tex., under commercial practice. The plants were initially grown in a polyethylene-covered greenhouse and then moved to a field situation. In the greenhouse, day and night temperatures ranged from 18 to 21.degree. C. and 14 to 17.degree. C., respectively, and light levels were maintained at 3,500 4,000 footcandles. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
