USPP20340P2 - Delphinium plant named ‘Moon Light’ - Google Patents

Abstract

A new and distinct Delphinium hybrid cultivar named ‘Moon Light’ is disclosed, characterized by an upright plant habit, vigorous growth and large lavender flowers with a large quantity of petals. The new cultivar produces strong flower stems, freely and continuously flowering from early through late Summer. The new variety is a Delphinium hybrid, suitable for garden or outdoor container use.

Description

Latin name of the genus and species: Delphinium hybrid.

Variety denomination: ‘Moon Light’.

BACKGROUND OF THE INVENTION

The new variety was discovered, by the inventor, as the result of a hand crossed, planned breeding program in Scotland. The parent varieties are both unnamed, undistributed proprietary seedlings. The discovery of the new variety was made by the inventor, Tony Coakley in August 2001 in a cultivated field of Delphiniums in Glasgow, Scotland.

Asexual reproduction of the new cultivar ‘Moon Light’ by tissue culture was performed in the Netherlands following selection and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Moon Light’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

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

• • 1. Upright plant habit.
  • 2. Vigorous growth habit.
  • 3. Strong flower stem.
  • 4. Freely and continuous flowering habit.
  • 5. Increased number of petals.
  • 6. Large individual flower size.

Plants of the new cultivar ‘Moon Light’ are similar to plants of the seed parent variety, an unnamed Delphinium hybrid in most horticultural characteristics; however, flowers of the new variety have more petals, and a stronger, more consistent color.

Plants of the new cultivar ‘Moon Light’ are similar to plants of the pollen parent variety, an unnamed Delphinium hybrid in most horticultural characteristics; however, flowers of the new variety have more petals, and a stronger, more consistent color.

The inventor is unaware of similar commercial varieties for comparison to ‘Moon Light.’ The strong flowering stems, unique flower coloration and increased petal count make the new cultivar unlike other Delphiniums in the trade.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Moon Light’ grown outdoors in Scotland. The pot size is a 1 liter container. The plant shown is approximately 9 months. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
