Description

Latin name of the genus and species: Mandevilla hybrida.

Variety denomination: ‘Scarlet Velvet’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program, with the objective to produce new Mandevilla varieties for small pot production. The new variety resulted from a crossing performed in August 2003 in Hawthorne, Fla. The seed and pollen parent is the Mandevilla hybrid ‘Red Velvet’, U.S. Plant Pat. No. 12,238. The new variety was selected April 2006, by the inventor, John Gray in a commercial nursery in Hawthorne, Fla.

Asexual reproduction of the new cultivar ‘Scarlet Velvet’ by vegetative cuttings was performed at a commercial nursery in Hawthorne, Fla. in June 2006 and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘Scarlet Velvet’ 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 ‘Scarlet Velvet’. These characteristics in combination distinguish ‘Scarlet Velvet’ as a new and distinct Mandevilla cultivar:

    • 1. Distinctive flower coloration, opening pink and turning red.
    • 2. Early blooming.
    • 3. Plant height at blooming of approximately 30 to 45 cm.
    • 4. Moderate branching and growth characteristics.

PARENT COMPARISON

Plants of the new cultivar ‘Scarlet Velvet’ are similar to plants of the parent variety, Mandevilla hybrid ‘Red Velvet’ in most horticultural characteristics, however, plants of the new cultivar ‘Scarlet Velvet’ have smaller flowers and smaller leaves. Additionally, ‘Scarlet Velvet’ flowers earlier than the parent variety.

COMMERCIAL COMPARISON

Plants of the new Mandevilla can be compared to the commercial variety ‘Sunmandecrim’ U.S. Plant Pat No. 15,539. Plants of the new cultivar ‘Scarlet Velvet’ are similar to plants of ‘Sunmandecrim’ in most horticultural characteristics, however, plants of the new cultivar have flowers that open pink and turn red, whereas ‘Sunmandecrim’ open red and remain red. Additionally, the new cultivar has a much less aggressive growth habit than ‘Sunmandecrim.’

Plants of the new cultivar can also be compared to the commercial variety ‘Red Velvet Petite’ U.S. Plant Pat. No. 12,813. ‘Scarlet Velvet’ is similar to ‘Red Velvet Petite’ in most horticultural characteristics, however, ‘Red Velvet Petite’ has an aggressive vining habit, whereas ‘Scarlet Velvet’ has a moderate vining habit. Additionally, ‘Scarlet Velvet’ flowers earlier than ‘Red Velvet Petite.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Scarlet Velvet’ grown in a poly greenhouse with 30% shade, in a 12 cm pot. Age of the plant photographed is approximately 7 months from a rooted cutting. The photographs were 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.

 DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Scarlet Velvet’ plants grown in a greenhouse in Hawthorne, Fla. The growing temperature ranged from 30° C. to 40° C. during the day and approximately 25° C. at night. The greenhouse is a poly covered with 30% shade. Measurements and numerical values represent averages of typical plant types. No growth retardants were used.
