ABSTRACT:

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Ornithogalum plant, botanically known as
Ornithogalum hybrida
, and hereinafter referred to by the name ‘Chesapeake Blaze’.
The new Ornithogalum is a product of a planned breeding program conducted by the Inventors in Beltsville, Md. and Escondido, Calif. The objective of the breeding program was to create newly freely-flowering interspecific Ornithogalum hybrids with unique and desirable flower colors.
The new Ornithogalum originated from a cross made by the Inventors of the
Ornithogalum hybrida
cultivar Kewensis (
Ornithogalum thyrsoides×O. dubium
), not patented, as the male, or pollen, parent with the
Ornithogalum hybrida
cultivar Chesapeake Sunset (
Ornithogalum dubium×O. multifolium
), U.S. Plant patent application Ser. No. 09/765,317, as the female, or seed, parent. The cultivar Chesapeake Blaze was discovered and selected by the Inventors as a flowering plant within the progeny of the stated cross in a controlled environment in Beltsville, Md. in 1994.
Asexual reproduction of the new Ornithogalum by tissue culture in a controlled environment in a laboratory in Beltsville, Md., has shown that the unique features of this new Ornithogalum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘Chesapeake Blaze’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, and water or nutritional status without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Chesapeake Blaze’. These characteristics in combination distinguish ‘Chesapeake Blaze’ as a new and distinct Ornithogalum:
1. Strong, upright and long scapes.
2. Dense corymbose racemes with numerous soft orange- colored flowers.
3. Glossy dark green leaves.
In side-by-side comparisons conducted by the Inventors in Beltsville, Md., plants of the new Ornithogalum differ from plants of the female parent, the cultivar Chesapeake Sunset, in the following characteristics:
1. Plants of the new Ornithogalum have longer leaves than plants of the cultivar Chesapeake Sunset.
2. Plants of the new Ornithogalum have longer scapes than plants of the cultivar Chesapeake Sunset.
3. Plants of the new Ornithogalum have a denser (less open) flower display than plants of the cultivar Chesapeake Sunset.
In side-by-side comparisons conducted by the Inventors in Beltsville, Md., plants of the new Ornithogalum differ from plants of the male parent, the cultivar Kewensis, in the following characteristics:
1. Plants of the new Ornithogalum are more freely flowering than plants of the cultivar Kewensis.
2. Plants of the new Ornithogalum have shorter scapes than plants of the cultivar Kewensis.
3. Plants of the new Ornithogalum have a denser (less open) flower display than plants of the cultivar Kewensis.
4. Plants of the new Ornithogalum have soft orange-colored flowers whereas plants of the cultivar Kewensis have cream-colored flowers.
