ABSTRACT:
Botanical classification/cultivar designation:
Hibiscus rosa
-
sinensis
cultivar Dallas.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Hibiscus
, botanically known as
Hibiscus rosa
-
sinensis
, and hereinafter referred to by the name ‘Dallas’.
The new
Hibiscus
is a product of a planned breeding program conducted by the Inventor in Amstelveen, The Netherlands. The objective of the breeding program is to create new compact freely-branching and freely-flowering
Hibiscus
cultivars appropriate for container production.
The new
Hibiscus
originated from a cross-pollination made by the Inventor in Amstelveen, The Netherlands in 1999, of a proprietary
Hibiscus rosa
-
sinensis
selection, identified as code number 30.12.731, not patented, as the female, or seed, parent with a proprietary
Hibiscus rosa
-
sinensis
selection, designated as code number 52.81.695, not patented, as the male, or pollen, parent. The cultivar Dallas was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Amstelveen, The Netherlands, in 2000.
Asexual reproduction of the new
Hibiscus
by vegetative terminal cuttings taken in a controlled environment in Amstelveen, The Netherlands since 2000, has shown that the unique features of this new
Hibiscus
are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Dallas has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature 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 ‘Dallas’. These characteristics in combination distinguish ‘Dallas’ as a new and distinct cultivar:
1. Compact, upright and uniform plant habit that is appropriate for container production.
2. Freely branching habit.
3. Glossy medium green-colored leaves.
4. Freely and continuous flowering habit.
5. Golden yellow-colored flowers.
6. Good resistance to flower bud abscission.
Compared to plants of the parents, the propietary
Hibiscus
selections, plants of the new
Hibiscus
are more upright, more freely branching, and more freely flowering.
Plants of the new
Hibiscus
are similar to plants of the
Hibiscus
cultivar Chicago, disclosed in U.S. Plant Pat. No. 14,215. However, in side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new
Hibiscus
differed from plants of the cultivar Chicago in the following characteristics:
1. Plants of the new
Hibiscus
were taller than plants of the cultivar Chicago.
2. Leaves of plants of the new
Hibiscus
were narrower and lighter green in color than leaves of plants of the cultivar Chicago.
3. Leaf petioles of plants of the new
Hibiscus
were shorter and darker green in color than leaf petioles of plants of the cultivar Chicago.
4. Plants of the new
Hibiscus
were more freely flowering than plants of the cultivar Chicago.
5. Flowers of plants of the new
Hibiscus
were lighter yellow in color than flowers of plants of the cultivar Chicago.
6. Flower peduncles of plants of the new
Hibiscus
were shorter, thinner and darker green in color than flower peduncles of plants of the cultivar Chicago.
