ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of winter-hardy Hibiscus, or Rose Mallow, botanically known as
Hibiscus moscheutos
, and hereinafter referred to by the cultivar name ‘Plant No. 179’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Park Ridge, Ill. The objective of the breeding program is to create new Hibiscus cultivars having large flat flowers with overlapping petals, long-lasting flowers, long flowering period and attractive flower colors.
The new cultivar originated from a cross made by the Inventor in Park Ridge, Ill., of the nonpatented
Hibiscus moscheutos
cultivar ‘Red Plate’, as the female, or seed, parent with the nonpatented
Hibiscus moscheutos
cultivar ‘Bills's Giant White’ as the male, or pollen, parent.
The cultivar ‘Plant No. 179’ was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Park Ridge, Ill. in 1993.
Compared to plants of the male parent, the cultivar ‘Bill's Giant White’, and the female parent, the cultivar ‘Red Plate’, plants of the new Hibiscus have larger flowers, flatter flowers, a longer flowering period, maintain the flat flower shape longer and differ in flower color.
Asexual reproduction of the new cultivar by root crown divisions and by terminal and stem cuttings taken in a controlled environment in Park Ridge, Ill., has shown that the unqiue features of this new Hibiscus are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘Plant No. 179’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, nutrition and water status without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Plant No. 179’. These characteristics in combination distinguish ‘Plant No. 179’ as a new and distinct cultivar:
1. Plant height of about 3.5 to 5.5 feet.
2. Very large flat flowers with fully overlapping petals and vibrant pink in color.
3. Flowers that maintain their flat shape for up to two days.
4. Long flowering period.
5. Resistant to diseases and insects common to Hibiscus.
6. Tolerant to humidity extremes.
7. Tolerant to drought and flooding.
8. Tolerant to temperature extremes, plants will tolerate temperature ranges from −25° to 100° F.
9. Roots are not attractive to rodents.
Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar ‘Morrison-Gilberg (IV)’, disclosed in U.S. Plant Pat. No. 11,165. In side-by-side comparisons conducted in Pacific, Mo., plants of the new Hibiscus are more rounded in plant shape, have more entire petal margins, more ruffled petals, and more prominent petal veins than plants of the cultivar ‘Morrison-Gilberg (IV)’.
