Abstract: A new plant variety of Loropetalum chinense variety rubrum characterized by its sectoral Yellow variegation.
Claim: I claim:

1. A new plant variety of Loropetalum chinense variety rubrum of the variety substantially as shown and described.
Description: BACKGROUNDOF THE INVENTION

The present invention relates to a new and distinct variety of Loropetalum chinense variety rubrum Yieh and was discovered as a branch sport of an unnamed variety of Loropetalum chinense var. rubrum (unpatented) in Saitama Prefecture, Japan. The varietal denomination of the new variety is `MOSAIC`.

The genus Loropetalum is included in the family Hamamelidaceae that comprises about 15 genera of shrubs and trees growing in the northern hemisphere. Loropetalum comprises one (1) species of evergreen shrub or small tree, which possessesdesirable ornamental characteristics. Loropetalum was first introduced to Europe as an ornamental plant the 1880s, and is believed to have been cultivated in North America since the early 1930s.

Loropetalum chinense var. rubrum is a native of China, and was first discovered in 1928 in Hunan Province. It was rediscovered in the late 1980s and subsequently introduced to the United States. Loropetalum chinense var. rubrum generally hasalternate, ovate leaves to about 6 cm long and about 3 cm wide. The plant is evergreen or partly evergreen depending on winter temperature. Leaf color ranges from light to dark Burgundy, occasionally Green, depending on light intensity, culturalconditions and cultivar. Shoots are slender, Brown, and densely pubescent, pith is solid. Leaves are generally densely pubescent overall.

Flowers of Loropetalum chinense var. rubrum are perfect, having 4-strap like petals which are about 2 cm long and about 0.3 cm wide. Three (3) to six (6) flowers are together in each leaf axil. Pedicel and calyx have a White pubescence. Flower color is Pinkish to Reddish Purple depending on the cultivar. Flowering is heaviest in early spring.

SUMMARY OF THE INVENTION

The new variety was discovered as a branch sport, and differs from other cultivars known to the inventor by its sectoral Yellow leaf variegation. Asexual reproduction of the new variety by stem cuttings performed in Kawaguchi City, SaitamaPrefecture, Japan; and Fulshear, Tex. have confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations and that the new variety reproduces true to type.

COMPARISON WITH PARENT

`MOSAIC` is distinguished from its parent and all other varieties of Loropetalum chinense var. rubrum of which I am aware by its sectoral Yellow variegation. In contrast, the parent of `MOSAIC` exhibits solid Purple foliage. Named varietiessimilar to the parent include Loropetalum chinense var. rubrum `Ruby` (unpatented), and `Hines Purpleleaf` (unpatented), both of which exhibit solid Purple foliage.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photographic illustration shows a plant of the new cultivar as true to color as is reasonably possible to make in an illustration of this character.

FIG. 1 illustrates the distinctive sectoral Yellow leaf variegation.

DESCRIPTION OF THE NEW VARIETY

Loropetalum chinense var. ruburm `MOSAIC` has not been observed under all possible environmental, cultural and light conditions. The following observations and descriptions are of two-year-old plants grown in 5-gallon nursery containers inFulshear, Tex. Phenotypic expression may vary with light intensity, cultural, and environmental conditions. In this description, color references are to The Royal Horticultural Society Colour Chart (1995) and terminology used in the color descriptionsherein refers to plate numbers in this color chart.

As with many plants in the Hamamelidaceae family, phenotypic characteristics can be dramatically different in terms of growth morphology. Botanical classification: Loropetalum chinense var. rubrum `MOSAIC`. Parentage.--Branch sport of anunnamed variety of Loropetalum chinense var. rubrum (unpatented). Propagation.--Vegetative cuttings. Plant: Size.--To about 5 feet tall and about 6 to 8 feet wide. Habit.--Young plants exhibit pendulous growth habit. Once plant is established, plantexhibits upright growth habit on growth. Branching: Dense, overall mounding to upright branching habit. Lateral branches.--Multi-branched shrub. Typical Branch Quantity: More than 1,000 branches and stems. Observed branch quantity.--More than 1,000branches and stems. Size.--Typical branch is about 1 m long, pendulous; diameter about 1 cm; apex is typically 1 mm or less. Branch coloration.--Near Grayed-Orange Group 166A. Leaf: Shape.--Ovate to obovate. Size.--Young foliage: Length about 1.4 cm;width about 1 cm wide. Mature foliage: Length about 3.4 cm; width about 2.2 cm. Arrangement.--Simple, alternate along the stem. Margin.--Entire, with stellate hairs. Texture.--Adaxial: coriaceous; sparsely pubescent with stellate hairs. Apex.--Acuteto obtuse. Base.--Obtuse, occasionally unequal. Color: Color varies with intensity of sunlight and cultural conditions. The following color readings were taken on Sep. 28, 2001 in full sun of a specimen grown in Fulshear, Tex. Sectoral Yellowvariegations emerges as foliage reaches maturity. The amount and precise pattern of variegation varies from leaf to leaf, but generally covers about 50% of the leaflets. New foliage.--Adaxial: Near Greyed-Purple Group 187A. Abaxial: Near Greyed-PurpleGroup 183C. Mature foliage.--Adaxial: Background color mostly near Yellow-Green Group 147A with some areas near Yellow-Green Group 145C and 148B; variegated areas vary from near Yellow Group 4C with some areas near Yellow Group 7B and 9C. Abaxial:Background color near Yellow-Green Group 148C; variegated areas near Yellow Group 4C and 10C. Venation pattern.--Pinnate. Petioles.--Size: Length between 2 to 4 mm; diameter about 1 mm. Color Young foliage: Near Greyed-Red Group 182B. Mature foliage:Near Green Group 139B. Stipules.--Between 2 to 3 mm; color near Yellow-Green Group 146C. Internodes.--Between 0.5 to 2 cm. Hardiness.--USDA Zone 7 (0.degree. F. to 7.degree. F.). Vigor.--Moderate. Pests/diseases.--None noted. Inflorescence: Bloomperiod.--Between March to April in Fulshear, Tex. with light repeat blooming throughout the growing season.
