Abstract: A new and distinct cultivar of Hypericum plant named `Esmmayor`, characterized by its upright plant habit; strong flowering stems; vigorous growth habit; dark green-colored leaves; red-colored fruits; good postproduction longevity; and tolerance to wind and rain.
Claim: It is claimed:

1. A new and distinct cultivar of Hypericum plant named `Esmmayor`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Hypericum androsaemum cultivar Esmmayor.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum androsaemum, commercially used as cut stems with fruits, and hereinafter referred to by the name `Esmmayor`.

The new Hypericum is a product of a planned breeding program conducted by the Inventor in El Quinche, Pichincha, Ecuador. The objective of the breeding program was to develop cut Hypericum varieties with strong foliage and attractive fruitcoloration.

The new cultivar originated from a cross-pollination made by the Inventor in August, 1999 of a proprietary selection of Hypericum androsaemum identified as Code 46, not patented, as the female, or seed, parent with an unknown selection ofHypericum androsaemum, not patented, as the male, or pollen, parent. The cultivar Esmmayor was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in El Quinche,Pichincha, Ecuador.

Asexual reproduction of the new Hypericum by terminal cuttings taken at El Quinche, Pichincha, Ecuador since February, 2001, has shown that the unique features of this new Hypericum are stable and reproduced true to type in successive generationsof asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Esmmayor`. These characteristics in combination distinguish `Esmmayor` as a new and distinct cultivar: 1. Upright plant habit, strongflowering stems. 2. Vigorous growth habit. 3. Dark green-colored leaves. 4. Red-colored fruits. 5. Good postproduction longevity. 6. Tolerance to wind and rain.

Plants of the new Hypericum differ from plants of the female parent selection identified as Code 46 in the following characteristics: 1. Plants of the new Hypericum are taller than plants of the female parent selection. 2. Plants of the newHypericum and the female parent selection differ in fruit coloration as plants of the female parent selection have bright red-colored fruits.

Plants of the new Hypericum can be compared to plants of the Hypericum cultivar Bosapin, disclosed in U.S. Plant Pat. No. 10,993. In side-by-side comparisons conducted in El Quinche, Pichincha, Ecuador, plants of the new Hypericum differedfrom plants of the cultivar Bosapin in the following characteristics: 1. Plants of the new Hypericum were more vigorous than plans of the cultivar Bosapin. 2. Plants of the new Hypericum had longer leaves than plants of the cultivar Bosapin. 3. Plants of the new Hypericum had smaller fruits than plants of the cultivar Bosapin. 4. Plants of the new Hypericum and the cultivar Bosapin differed in leaf and fruit coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hypericum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Hypericum.

The photograph at the top of the sheet comprises a side perspective view of a typical stem of `Esmmayor` in fruit.

The photograph at the bottom of the sheet is a close-up view of a typical cluster of fruits, the upper surface of a typical leaf, and the lower surface of a typical leaf of `Esmmayor`.

DETAILED BOTANICAL DESCRIPTION

The new Hypericum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in El Quinche, Pichincha, Ecuador, in an outdoor nursery and under commercial production practices. Plants were about one year old. During theproduction of the plants, day temperatures ranged from 12 to 30.degree. C. and day temperatures ranged from 5 to 12.degree. C. Plants were pinched about two weeks after planting. In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
