Loropetalum chinense variety rubrum named ‘Melting Pot’

Abstract

A new plant variety of Loropetalum chinense var. rubrum characterized by its white flowers and purple colored new foliage which matures to green.

Description

Classification: The present invention relates to a new Loropetalum chinense var. rubrum Yieh plant.

Variety denomination: The new plant has the varietal denomination ‘Melting Pot’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Loropetalum chinense variety rubrum Yieh and was discovered a branch sport of Loropetalum chinense ‘Shibori’ (unpatented) in Fulshear, Tex.

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 species of evergreen shrub or small tree, which possesses desirable ornamental characteristics. Loropetalum was first introduced to Europe as an ornamental plant the 1880's, and is believed to have been cultivated in North America since the early 1930's.

Loropetalum chinense var. rubrum is a native of China, and was first discovered in 1928 in Hunan province. It was rediscovered in the late 1980's and subsequently introduced to the United States. Loropetalum chinense var. rubrum generally has alternate, ovate leaves to 6 cm long and 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, cultural conditions 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 with four (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 Loropetalum chinense ‘Shibori’ (unpatented), which is a white and pink flowering plant (flowers were pink with white striping). The new variety differs from the parent and other cultivars known to the inventor by having white flowers and purple colored new foliage which matures to green. Asexual reproduction of the new variety by cuttings taken in Fulshear, Tex. and Vacaville, Calif. 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

‘Melting Pot’ is distinguished from its parent by its white flowers and purple colored new foliage which matters to green. In contrast, the parent of ‘Melting Pot’ has flower petals with a pink central stripe and white margins.

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 white colored flowers of the new variety.
