Miniature shrub rose plant named ‘ALTtictac’

A new and distinct cultivar of miniature shrub Rose plant named ‘ALTtictac’ is disclosed, characterized by distinctive pink and white striped flowers, blooming continuously from spring to autumn. Plants are dwarf and compact, with dark, glossy foliage exhibiting good resistance to blackspot disease and powdery mildew. The new variety is normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Rosa hybrida.

Variety denomination: ‘ALTtictac’.

BACKGROUND OF THE INVENTION

The new Rosa cultivar is a product of a planned breeding program conducted by the inventor, Peter Lim. The objective of the breeding program was to produce new garden rose varieties with striped petals, and glossy foliage. The cross resulting in this new variety was made June 28 of 2013.

The seed parent is an unnamed, unpatented miniature Rosa variety. The pollen parent is the unpatented Rosa ‘Love and Peace’. The new variety was selected in June 2014 by the inventor in a group of seedlings resulting from the 2013 crossing, in a nursery in Vista, California.

Asexual reproduction of the new cultivar has been performed by vegetative cuttings. This was first performed at a research greenhouse in Vista, California in June 2014 and has shown that the unique features of this cultivar are stable and reproduced true to type in more than 5 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘ALTtictac’ 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 ‘ALTtictac’. These characteristics in combination distinguish ‘ALTtictac’ as a new and distinct Rosa cultivar:

    • 1. Pink and white striped petals.
    • 2. Earlier blooming.
    • 3. Dark, glossy foliage resistant to blackspot and powdery mildew.
    • 4. Continuous flowering.
    • 5. Dwarf, compact size.
    • 6. Plants can be grown on their own roots; grafting is not required.

PARENT COMPARISONS

Plants of the new cultivar ‘ALTtictac’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘ALTtictac’ differ in the following:

    • 1. Flower color of the new variety is pink and white striped, while flower color of the seed parent is orange.

Plants of the new cultivar ‘ALTtictac’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘ALTtictac’ differs in the following;

    • 1. Flower color of the new variety is pink and white striped, while flower color of the pollen parent is pink and red striped.

COMMERCIAL COMPARISONS

Plants of the new cultivar ‘ALTtictac’ can be compared to the commercial variety Rosa ‘Stars ‘n’ Stripes’, U.S. Plant Pat. No. 4,029. These varieties are similar in most horticultural characteristics, however ‘ALTtictac’ differs in the following:

    • 1. Flower color of the new variety is pink and white striped, while flower color of this comparator is red and white striped.

Plants of the new cultivar ‘ALTtictac’ can also be compared to the commercial variety Rosa ‘POULTY019’, U.S. Plant Pat. No. 26,051. These varieties are similar in most horticultural characteristics, however ‘ALTTICTAC’ differs in the following:

    • 1. Flower color of the new variety is pink and white striped, while flower color of this comparator is red and white striped.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a close up of an individual flower of ‘ALTtictac’. The plant producing this flower is approximately 18 months old; the flower is approximately 5 days old from a colored bud stage and about 2 days from fully open. 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.
