Abstract

A new and distinct cultivar of Delphinium plant named ‘Delga Stam’, as described and illustrated, and particularly characterized by green leaf color, violet blue/greyed-green flower color, upward facing flowers, new flowers grow from the center of existing flower after 4-8 weeks, flowers are persistent without adding pretreatment, much higher stem production per plant.

Description

Latin name of the genus and species of the plant claimed: Delphinium hybrid.
Variety denomination: ‘Delga Stam’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Delphinium, botanically known as Delphinium hybrid and hereinafter referred to by the cultivar name ‘Delga Stam’.
The new Delphinium was discovered by the inventor, Irenaeus A. M. van Gaalen, in Den Hoorn, The Netherlands, in May 2001 as a plant within the progeny from the cross between Delphinium belladona ‘Völkerfrieden’ (female, unpatented) and Delphinium L. ‘Peacemaker’ (male, unpatented).
Asexual propagation of the new cultivar by vegetative cuttings cuttings taken at Den Hoorn, The Netherlands, 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 ‘Delga Stam’ 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 observations, measurements and values describe the new cultivar as grown in Den Hoorn, The Netherlands in a normal glass greenhouse under average day temperatures 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. The plant described was one year old and field grown under glasshouse structure.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Delga Stam’. These characteristics in combination distinguish ‘Delga Stam’ as a new and distinct cultivar:
1. green leaf color;
2. violet blue/greyed-green flower color;
3. upward facing flowers;
4: new flowers grow from the center of existing flower after 4-8 weeks;
5. flowers are persistent without adding pretreatment; and
6. much higher stem production per plant.
Compared to ‘Völkerfrieden’, ‘Delga Stam’ has upward facing flowers whereas ‘Volkerfrieden’ has horizontally facing flowers. The flower color of ‘Delga Stam’ is violet-blue with greyed-green whereas the flower color of ‘Volkerfrieden’ is blue. New flowers of ‘Delga Stam’ grow continuously from the center of existing flowers after 4-8 weeks with sufficient light and temperature; ‘Volkerfrieden’ does not do this. The flowers of ‘Delga Stam’ are persistent unlike the flowers of ‘Volkerfrieden’. Volkerfrieden needs pretreatment after cutting to avoid early flower drop, ‘Delga Stam’ does not need pretreatment. ‘Delga Stam’ has a much higher temperature resistance than ‘Volkerfrieden’. ‘Delga Stam’ produces significantly more stems than ‘Volkerfrieden’.
Compared to Delphinium belladonna ‘Peacemaker’, the sepals of ‘Delga Stam’ are violet blue with a broad greyed-green lateral band in the center whereas ‘Peacemaker’ has violet-blue sepals. The sepal shape of ‘Delga stam’ is elliptic whereas the sepal shape of ‘Peacemaker’ is obovate. ‘Delga Stam’ has upward facing flowers whereas ‘Peacemaker’ has horizontally facing flowers. New flowers of ‘Delga Stam’ grow from the center of existing flowers after 4-8 weeks with sufficient light and temperature; ‘Peacemaker’ does not do this. The flowers of ‘Delga Stam’ are persistent unlike the flowers of ‘Peacemaker’. ‘Peacemaker’ needs pretreatment after cutting to avoid early flower drop, ‘Delga Stam’ does not need pretreatment.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawings shows typical flower and foliage characteristics of ‘Delga Stam’ with colors being as true as possible with illustrations of this type. The drawing on the left side of the first sheet shows a plant with mature flowers grown in a green house. The drawing on the right side of the first sheet shows a close-up of flowers between immature and mature stage. The drawing on the left side of the second sheet shows a comparison between ‘Volkerfrieden’ (left) and ‘Delga Stam’ (right). The drawing on the top middle of the second sheet shows a close-up of an immature flower. The drawing on the top right of the second sheet shows a close-up of an immature flower. The drawing on the bottom right of the second sheet show a close-up of a mature flower.
