ABSTRACT:

FIELD OF THE INVENTION
The present invention comprises a new and distinct cultivar of
Ornithogalum dubium
which is named ‘Namib Sunrise’. Its market class is that of potted plants or bulbs. ‘Namib Sunrise’ is intended for use in landscaping, and as a decorative flowering potted plant.
DESCRIPTION OF PRIOR ART
‘Namib Sunrise’ was invented by the selection of a single plant that originated from the progeny of the parent plants that were allowed to open-pollinate within the group. The pollination occurred during 1991 at Elsenberg, Western Cape, Republic of South Africa. ‘Namib Sunrise’ was bred and evaluated by Dr. Gail Littlejohn, a citizen of South Africa. ‘Namib Sunrise’ was first asexually propagated by Dr. E. L. Farringer and Mrs. C. F. Farringer. Dr. E. L. Farringer is a U.S. citizen, and Mrs. C. F. Farringer is a citizen of the Republic of South Africa.
‘Namib Sunrise’ is a selection of open-pollinated
Ornithogalum dubium
. The open pollination was achieved in a greenhouse, and was amongst a select population of
Ornithogalum dubium
individuals.
‘Namib Sunrise’ has been asexually reproduced in South Africa from 1997 onwards, using tissue culture. Approximately 20,000 plants have been grown, and these ‘Namib Sunrise’ propagules appear to be identical to the original plant in all distinguishing characteristics. Thus the clone appears stable.
‘Namib Sunrise’ is a bulbous plant with strap-like leaves of about 8 to 12 cm in length. In nature, it grows in winter and flowers in the spring (October in the Southern hemisphere at 32 degrees South). It produces a raceme somewhat corymbose in shape and lengthening with age to about 15-30 cm in height. Flowers are 2.8-3.5 cm in diameter and cup-shaped, with 15-20 flowers per inflorescence.
‘Namib Sunrise’ 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 Sunrise’ is adapted to Zone 8 of the Hardiness Map of the United States.
‘Namib Sunrise’ is distinguishable from other clones by the color of its flower, the size and shape of the flower raceme, and the size of individual flowers as well as the compact growth pattern of the leaves.
‘Namib Sunrise’ is distinguished from other
Ornithogalum dubium
cultivars by the following combination of traits:
Flower color: RHS25A orange clear throughout the flower, with no dark center or heart.
Flower size: 2.8-3.5 cm.
Flower shape: Cup-shaped.
Raceme size: 15-30 cm in height.
Raceme shape: Corymbose, lengthening with age.
Flowers per raceme: 15-20 [50-60].
Leaf size: 8-12 cm.
