Abstract

A new and distinct cultivar of Delphinium plant named ‘Delgaal’, as described and illustrated, and particularly characterized by its green leaves, violet-blue colors, upright growth habit, terminal raceme flower arrangement with approximately 22 flowers per main stem; and inflorescence of 40 cm in length (average) and 14 cm in diameter (average).

Description

Genus and species of the plant claimed: Delphinium L.
Variety denomination: Delgaal.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Delphinium, botanically known as Delphinium L., and hereinafter referred to by the cultivar name ‘Delgaal’.
The new Delphinium was discovered by the inventor in Den Hoorn, The Netherlands, in May, 2000 as a naturally occurring mutation from Delphinium belladonna ‘Völkerfrieden’ (unpatented).
Asexual propagation of the new cultivar by tissue culture conducted at Maasdijk, The Netherlands, starting in June 2000, has shown that the unique features of this new Delphinium are stable and reproduce true to type in successive generations.
BRIEF DESCRIPTION OF THE INVENTION
Plants of the cultivar ‘Delgaal’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in the environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Delgaal’. These characteristics in combination distinguish ‘Delgaal’ as a new and distinct cultivar:
1. upright growing
2. green leaf color
3. violet-blue flower color
4. terminal raceme flower arrangement with approximately 22 flowers per main stem; and
5. inflorescence 40 cm (average) and 14 cm in diameter (average).
Of the many commercial cultivars known to the present inventor, there are no widely know comparison varieties. The most similar in comparison to ‘Delgaal’ is cultivar Delphinium belladonna ‘Völkerfrieden’.
Compared to parental cultivar Delphinium belladonna ‘Völkerfrieden’ (unpatented) the flower color of ‘Delgaal’ is violet-blue whereas the flowers or ‘Völkerfrieden’ are dark blue. Another difference is that it has turned out that the lasting time of ‘Delgaal’ as a cutflower is some 20 percent longer than ‘Völkerfrieden’.
‘Delgaal’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Den Hoorn, The Netherlands in a normal glass greenhouse under average day temperatures of between 18 to 32 degrees Celsius and 10 to 18 degrees Celsius at night. No artificial lighting, photoperiodic treatments or other cultural or environmental treatments are conducted, no growth retardants are added. These conditions closely approximate those generally used in commercial practice.
BRIEF DESCRIPTION OF THE DRAWING(S)
The accompanying photographic drawings show typical flower and foliage characteristics of ‘Delgaal’ with colors being as true as possible with illustrations of this type. The measurements were taken in Den Hoorn, The Netherlands, in August 2001, 10 weeks after planting of tissue plants. The plants had not been pinched.
The first drawing shows a close up of a ‘Delgaal’ flower.
The second drawing shows a comparison between ‘Delgaal’ on the right, and the cultivar ‘Völkerfrieden’ on the left.
The third drawing shows plantings of ‘Delgaal’.
The fourth drawing shows a close-up side view of a ‘Delgaal’ flower.
