| Description: |
BACKGROUND OF THEINVENTION
The present invention relates to a new and distinct variety of Hibiscus Rosa-sinensis L., which was developed in a controlled breeding program in Webster, Tex. by the originator Mr. Barry Schlueter. The varietal denomination of the new varietyis `AMAZON QUEEN`.
The genus Hibiscus comprises about 250 species of herbs, shrubs and trees in warm temperate and tropical regions; with leaves usually simple, mostly palmately veined, lobed or parted; flowers mostly solitary in the leaf axils but sometimes inracemes, corymbs or panicles. Hibiscus is included in the family Malvaceae, which comprises about 95 genera of herbs, shrubs and trees originating in tropical and temperate regions. Hibiscus Rosa-sinensis is a glabrate shrub, seldom over 8 feet tall incultivation, but treelike to 15 feet or more in tropical regions. Leaves to 6 inches long, ovate, usually serrate, mostly glossy green. Flowers solitary in upper leaf axils.
The new Hibiscus is a product of a planned breeding program conducted by the inventor in Webster, Tex. The objective of the program was to create new Hibiscus selections with improved bloom quality, color and floriferousness, plants that can becommercially produced on their own root systems, and improved plant habit with regard to vigor and post-production longevity.
SUMMARY OF THE INVENTION
The new variety was discovered in a controlled breeding program of Hibiscus Rosa-sinensis and differs from its parents and other known cultivars of Hibiscus Rosa-sinensis by the following characteristics in combination: 1. Upright, compactsymmetrical plant habit that is suitable for container production; 2. Healthy green foliage; 3. Vigorous growth habit; 4. Large unique multi-colored flowers with predominantly orange petals and a red to pink fading center; and 5. Free-flowering.
Asexual reproduction of the new variety by stem cuttings, performed in Webster, Tex. and Fulshear, Tex. have confirmed that the distinctive characteristics of the new variety are stable and transmitted to succeeding generations, and the newvariety reproduces true to type.
COMPARISON WITH PARENTS AND OTHER VARIETIES
`AMAZON QUEEN` is distinguished from its female parent `SCHIZOPHRENIC` (unpatented) by having a more upright habit and its extremely fancy flower that is heavily ruffled and tufted; `SCHIZOPHRENIC` has a low growing habit and its flower is ablend of yellow, orange and pink. `AMAZON QUEEN` is distinguished from its male parent `LADY EMMA` (unpatented) by its improved branching habit and flower form. `LADY EMMA` is extremely upright, sending out very few lateral branches, and its bloom isso heavily textured that it often fails to open properly.
Plants of `AMAZON QUEEN` can be compared to plants of the cultivar `GREAT SATAN` (unpatented). However, in side-by-side comparisons conducted in Webster, Tex., plants of the new cultivar differ from plants of the cultivar `GREAT SATAN` in thefollowing characteristics: 1. Flower color of `AMAZON QUEEN` are brighter in color than flowers of `GREAT SATAN`; 2. Plants of `AMAZON QUEEN` are easier to clone via rooting than plants of the cultivar `GREAT SATAN`; and 3. Plants of `AMAZON QUEEN`possess healthier foliage and a better growth habit than the cultivar `GREAT SATAN`.
BRIEF DESCRIPTION OF ILLUSTRATIONS
The accompanying illustrations show a specimen of the new cultivar in a photographic illustration as true to color as is reasonably possible to make in an illustration of this character.
FIG. 1 illustrates a side perspective view of a typical plant of `AMAZON QUEEN`;
FIG. 2 illustrates the scale of a typical flower of `AMAZON QUEEN`;
FIG. 3 illustrates the typical young to mature foliage of `AMAZON QUEEN`; the abaxial and adaxial surfaces are shown at each stage; and
FIG. 4 illustrates a dissected flower of `AMAZON QUEEN`, including shape and size of petals and characteristics of the reproductive structures.
DESCRIPTION OF THE NEW VARIETY
`AMAZON QUEEN` has not been observed under all possible environmental, cultural and light conditions. The following observations and descriptions are of plants grown in Fulshear, Tex., in October 2001, under polypropylene shadecloth providing a30% light reduction, and under conditions which closely approximate commercial production. Plants described were approximately 1-year old and in a Number 3 nursery container.
In this description, color references are to The Royal Horticultural Society Colour Chart (1995) and terminology used in the color descriptions herein refers to plate numbers in this color chart. Phenotypic expression may vary with lightintensity, cultural and environmental conditions. Classification: Botanical.--Hibiscus Rosa-Sinensis L. `AMAZON QUEEN`.
