Abstract

A distinct cultivar of Dahlia plant named Bawhi, characterized by its compact growth habit; small leaves and inflorescences that are porportional to the overall plant size; strong healthy foliage; ease of propagation; and light yellow ray florets that appear white at a distance with dark yellow disc florets.

Description

The present invention relates to a new and distinct cultivar of Dahlia plan, botanically known as Dahlia hybrida, and hereinafter referred to by the cultivar name Bawhi.
The new Dahlia is a product of a planned breeding program conducted by the inventor in Quedlinburg, Germany. The objective of the breeding program was to create new Dahlia cultivars having a compact growth habit suitable of 7 to 9-cm container production, small inflorescences, desirable inflorescence colors, and inflorescences and foliage with good substance.
The new Dahlia originated from a cross made by the inventor of the inventor's proprietary Dahlia seedling selections. The cultivar Bawhi was discovered and selected by the inventor as a flowering plant within the progeny of this cross in a controlled environment in Quedlinburg, Germany.
Asexual reproduction of the new Dahlia by terminal cuttings taken at Quedlinburg, Germany, has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and are determined to be the unique characteristics of Bawhi. These characteristics in combination distinguish Bawhi as a new and distinct cultivar:
1. Compact growth habit, suitable for 7 to 9-cm containers. Plants do not require growth retardants.
2. Small leaves and inflorescences that are proportional to the overall plant size.
3. Strong healthy foliage.
4. Excellent rooting and easy to propagate.
5. Light yellow ray florets with dark yellow disc florets. Ray florets appear white at a distance.
The new Dahlia 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.
Compared to the female parent, plants of the new Dahlia have smaller inflorescences. Plants of the new Dahlia differ from the male parent in ray floret color.
Plants of the new Dahlia are similar to the cultivar Elly (disclosed in U.S. Plant Pat. No. 6,767) in ray floret color. However, in side-by-side comparisons conducted in Quedlinburg, Germany, under commercial practice, plans of the new Dahlia differed from plants of the cultivar Elly in the following characteristics:
1. Plants of the new Dahlia are more compact and shorter than plants of the cultivar Elly.
2. Leaves of plants of the new Dahlia are smaller than leaves of plants of the cultivar Elly.
3. Inflorescences of plants of the new Dahlia are smaller than inflorescences of plants of the cultivar Elly.
4. Ray floret color is more yellow on plants of the new Dahlia compared to ray floret color of plants of the cultivar Elly.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompaning colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The FIG. 1 photograph comprises a top perspective view of a typical flowering plant of Bawhi.
The FIG. 2 photograph comprises a top perspective view of immature (top) and mature (bottom) leaves. The upper (left) and under (right) sides of the leaves are shown.
The FIG. 3 photograph comprises a side perspective view of developing inflorescences. From right to left are a flower bud at the green stage, an opening flower bud, a developed inflorescence with ray florets removed, and excised ray florets and stamen.
The FIG. 4 photograph comprises a top perspective view of developing inflorescences. From right to left are a flower bud at the green stage, an opening flower bud, a developed inflorescence with ray florets removed, and a developing inflorescence with ray florets intact. Foliage and floret colors in the photographs may appear different from the actual colors due to light reflectance.
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. The following observations and measurements describe plants grown in Quedlinburg, Germany, during the winter season under commercial practice in a glass-covered greenhouse with average night temperatures of 15C, average day temperatures of 20C, and light levels of 2,500 lux.
