plant named ‘ALTMAMAMIYA’

A new and distinct cultivar of Hibiscus plant named ‘ALTMAMAMIYA’ is disclosed, characterized by strongly ruffled, dark orange-red blooms with a darker base. Plants are dwarf and compact in habit, with dark, glossy foliage that is resistant to leaf spot disease. Flowering is continuous during the flowering season. The new variety is a Hibiscus, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Hibiscus rosa-sinensis.

Variety denomination: ‘ALTMAMAMIYA’.

BACKGROUND OF THE INVENTION

The new Hibiscus cultivar is a product of a planned breeding program conducted by the inventor, Peter Lim. The objective of the breeding program was to produce vigorous Hibiscus rosa-sinensis cultivars with healthy foliage. The cross resulting in this new variety was made Jul. 15, 2015.

The seed parent is the unpatented Hibiscus rosa-sinensis ‘City of New York’. The pollen parent is the variety Hibiscus rosa-sinensis ‘Antigua Wind’, U.S. Plant Pat. No. 23,656. The new variety was identified and selected as a potentially interesting selection in September of 2017. Selection was made at a commercial nursery in Vista, Calif.

Asexual reproduction of the new cultivar ‘ALTMAMAMIYA’ was first performed on September of 2017 in Vista, Calif., by vegetative cuttings. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ALTMAMAMIYA’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘ALTMAMAMIYA’. These characteristics in combination distinguish ‘ALTMAMAMIYA’ as a new and distinct Hibiscus cultivar:

    • 1. Dark orange-red petals which are tightly overlapped and have a darker base, forming a dark eye.
    • 2. Ruffled petals.
    • 3. Dwarf compact bush constantly in bloom.
    • 4. Dark dense glossy foliage which is highly disease resistant.

PARENT COMPARISONS

Plants of the new cultivar ‘ALTMAMAMIYA’ are similar to the seed parent, in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:

    • 1. Flowers of the new variety are orange-red, flowers of the seed parent are red.

Plants of the new cultivar ‘ALTMAMAMIYA’ are similar to the pollen parent, in most horticultural characteristics. However, characteristics of the new cultivar differ in the following:

    • 1. Flowers of the new variety are orange-red, flowers of the pollen parent are rosy red.
    • 2. Petals of the new variety are more ruffled than petals of the pollen parent.

COMMERCIAL COMPARISON

Plants of ‘ALTMAMAMIYA’ are similar in some horticultural characteristics to the variety Hibiscus ‘Fire Wind’, U.S. Plant Pat. No. 31,123. The new variety, however, differs in the following:

    • 1. Flowers of ‘ALTMAMAMIYA’ are a different color red than flowers of ‘Fire Wind’.
    • 2. Plants of ‘Fire Wind’ have a taller growth habit than plants of ‘ALTMAMAMIYA’.
    • 3. Foliage of ‘ALTMAMAMIYA’ is darker green than foliage of ‘Fire Wind’.

Plants of ‘ALTMAMAMIYA’ are similar in some horticultural characteristics to the variety Hibiscus ‘Hot to Trot’, unpatented. The new variety, however, differs in the following:

    • 1. Flowers of ‘ALTMAMAMIYA’ are smaller than flowers of ‘Hot to Trot’.
    • 2. Plants of ‘Hot to Trot’ have a taller growth habit than plants of ‘ALTMAMAMIYA’.
    • 3. Flowers of ‘ALTMAMAMIYA’ have a darker eye not found on ‘Hot to Trot’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a typical flower of ‘ALTMAMAMIYA’ from a plant grown outdoors at a commercial nursery in Vista, Calif. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
