Description

BOTANICAL CLASSIFICATION

Phalaenopsis hybrid cultivar Artemisa.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phalaenopsis, botanically known as Phalaenopsis hybrid and hereinafter referred to by the name ‘Artemisa’.

The new Phalaenopsis is a product of a planned breeding program conducted by the Inventor in Lochristi, Belgium. The objective of the breeding program is to create new compact Phalaenopsis cultivars.

The new Phalaenopsis originated from a cross made by the Inventor in June, 1994, in Lochristi, Belgium, of a proprietary Phalaenopsis hybrid selection identified as MFB001 as the female, or seed, parent with a proprietary Phalaenopsis hybrid selection identified as MFR035 as the male, or pollen, parent.

The new Phalaenopsis was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Lochristi, Belgium. The selection of this plant was based on its compact plant habit and purple flowers.

Asexual reproduction of the new Phalaenopsis by tissue culture in a controlled environment in Lochristi, Belgium, has shown that the unique features of this new phalaenopsis are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

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

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Artemisa’. These characteristics in combination distinguish ‘Artemisa’ as a new and distinct cultivar:

1. Upright and compact plant habit with relatively short flower stems.

2. Short dark green leaves.

3. Showy purple-colored flowers.

4. Freely flowering, about 10 to 15 flowers and flower buds per raceme.

5. Excellent flower longevity, flowers last about 8 weeks on the plant.

Plants of the new Phalaenopsis can be compared to plants of the female parent, the selection MRB001. In side-by-side comparisons conducted in Lochristi, Belgium, plants of the new Phalaenopsis are more compact, have shorter flowering stems and have more rounded leaf apices than plants of the selection MRB001. Plants of the new Phalaenopsis can be compared to plants of the white-flowered male parent, the selection MFR035. In side-by-side comparisons conducted in Lochristi, Belgium, plants of the new Phalaenopsis have darker green leaves than plants of the selection MFR035.

DETAILED BOTANICAL DESCRIPTION

The aforementioned and following observations, measurements, values, and comparisons describe plants grown in Lochristi, Belgium, in a glass-covered greenhouse in 13-cm containers under conditions which approximate commerical Phalaenopsis production conditions. Plants were grown for about 45 weeks after planting. During the first 25 weeks of production, day and night temperatures averaged 25° C.; during the next four weeks of production, day and night temperatures averaged 18° C.; and for the last weeks of production, day and night temperatures averaged 22° C. 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.
