ABSTRACT:

FOREIGN PRIORITY
This application claims benefit and priority of Certificate of Grant of a Plant Breeder's Right for Namib Sun, issued Apr. 3, 2000 (South Africa), application for which was filed Oct. 22, 1998.
FIELD OF THE INVENTION
The present invention comprises a new and distinct cultivar of
Ornithogalum dubium
which is named ‘Namib Sun’. Its market class is that of potted plants or bulbs. ‘Namib Sun’ is intended for use in landscaping, and as a decorative flowering potted plant.
DESCRIPTION OF PRIOR ART
‘Namib Sun’ was invented by hand pollination between two subspecies of
Ornithogalum dubium
. The cross pollination was conducted during 1994 at Elsenberg, Western Cape, Republic of South Africa. ‘Namib Sun’ was bred and evaluated by Dr. Gail Littlejohn, a citizen of South Africa. ‘Namib Sun’ was first asexually propagated by Dr. Farringer and Mrs. Farringer. Dr. E. L. Farringer is a U.S. citizen, and Mrs. C. F. Farringer a citizen of the Republic of South Africa.
‘Namib Sun’ is a cross of A2 (unpatented) and 91H969-3 (unpatented) Ornithogalum. A2 was an
Ornithogalum dubium
selection which was chosen for its large petal size, its yellow flowers, and its long flower raceme. 91H969-3 was an
Ornithogalum dubium
selection which was chosen for its deep yellow flower color.
‘Namib Sun’ has been asexually reproduced in South Africa from 1997 onwards, using tissue culture. Approximately 20,000 plants have been grown, and these ‘Namib Sun’ propagules appear to be identical to the original plant in all distinguishing characteristics. Thus the clone appears stable.
SUMMARY OF THE INVENTION
‘Namib Sun’ is a bulbous plant with strap-like leaves. In nature, it grows in winter and flowers in the spring (October in the Southern hemisphere at 32 degrees South). It produces a long spike-shaped flower raceme of about 20 to 75 cm in height.
‘Namib Sun’ is cyclically dormant. Specifically, it is dormant in summer, and blooms every year. Plants in nature rarely live beyond 5-10 years due to pests. In a pest-free environment, plants will live in excess of 10 years.
‘Namib Sun’ is distinguishable from other clones by the color of its flower, the size of flower raceme, and the size of individual florets as well as the robust growth pattern of the leaves. In addition, the plant ‘Namib Sun’ itself is much more robust than most other
Ornithogalum dubium
varieties. ‘Namib Sun’ is adapted to Zone 8 of the Hardiness Map of the United States.
‘Namib Sun’ is distinguished from other
Ornithogalum dubium
cultivars by the following combination of traits:
Flower color: RHS7B yellow.
Flower size: 2-3 cm.
Flower shape: Cup-shaped.
Raceme size: 30-75 cm in height.
Flowers per raceme: 15-20 [50-60].
Leaf size: 20-30 cm.
