| Abstract: |
A new cultivar of Agapanthus named `White Heaven` that is characterized by an upright, clumping habit, green leaves and large many flowered flowerheads. In combination these traits set `White Heaven` apart from all other existing varieties of Agapanthus known to the inventor. |
| Claim: |
It is claimed:
1. A new and distinct variety of Agapanthus plant named `White Heaven` as described and illustrated. |
| Description: |
Genus: Agapanthus.
Species: africanus.
Denomination: White Heaven.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of lily-of-the-Nile grown for use as an ornamental for container, landscape or cut flowers. The new cultivar is known botanically as Agapanthus africanus and will hereinafter bereferred to as `White Heaven`.
`White Heaven` is a chance seedling that was discovered by the inventor in a cultivated area of Roelofarendsveen, The Netherlands in 1998. `White Heaven` was discovered as an individual chance seedling in an established block of unknowncultivars of Agapanthus africanus being grown for the purpose of cut flower production. `White Heaven` was selected, by the inventor, for the unique trait of large flower heads with 70-80 white flowers per inflorescence.
The new variety `White Heaven` is a chance hybrid that resulted from the open pollination of unknown cultivars of Agapanthus grown from bulbs in a cultivated area of The Netherlands. The female parent is presumed to be an unknown cultivar ofAgapanthus africanus and the male parent is presumed to be an unknown cultivar of Agapanthus africanus. The unique trait that distinguishes `White Heaven` from the parent plants, is the size of the flower head, which is 150% larger than the closestcomparison plant Agapanthus africanus `Albus` (unpatented).
`White Heaven` is an herbaceous perennial, exhibiting an upright clumping growth habit, large white flower heads and green foliage. The size of the flower head, distinguishes `White Heaven` from all other existing Agapanthus known to theinventor.
`White Heaven` was first asexually propagated in 1999 in a cultivated area of Roeloforendsveen, The Netherlands by the inventor. The method used for asexual propagation was division. Since that time under careful observation, successivegenerations have been determined stable and true to type. Asexual propagation can also be accomplished using the method of tissue culture.
The Inventor filed on May 28, 1999 Application Number 1999/0781 for a grant of European Community Plant Breeder's Rights. Application was granted on Mar. 5, 2001 (Grant Number 7,376). The Inventor has been engaged in the build-up of stock, bydivision, solely at Inventor's own nursery. No plants of `White Heaven` have been sold or otherwise distributed from the Inventor's nursery prior to May 13, 2003.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Agapanthus variety known as `White Heaven`. These traits in combination distinguish `White Heaven` from all other existing varietiesof Agapanthus known to the inventor. `White Heaven` has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance ingenotype. 1. Agapanthus `White Heaven` is evergreen. 2. Agapanthus `White Heaven` exhibits vertical scapes and large flower heads. 3. Agapanthus `White Heaven` exhibits 70-80 white flowers per inflorescence. 4. Agapanthus `White Heaven` exhibitsan upright and clumping habit. 5. Agapanthus `White Heaven` is an ornamental herbaceous perennial. 6. Agapanthus `White Heaven` exhibits green foliage. 7. Agapanthus `White Heaven` is suitable for cut flowers, and as a container or landscape plant. 8. Agapanthus `White Heaven` is 90 cm. in height and 75 cm. in width at maturity. 9. Agapanthus `White Heaven` is hardy to USDA Zone 8b.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new Agapanthus variety `White Heaven` at three years old and grown in a container, showing the colors as true as it is reasonably possible to obtain in colored reproductionsof this type.
The drawing on sheet 1 illustrates the entire plant in bloom from a side perspective.
The drawing on sheet 2 shows a close-up view of the flowers.
Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety `White Heaven`. The drawings were made using conventional photographic techniquesand although flower and foliage colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.
