The flowers are densely striated orange red approximately RHS Orange Red 33A on their inner surfaces, with a sharp white RHS 155C keel.

Description

Latin name of the genus and species of the plant claimed: ‘Miami’ is a new amaryllis plant that is a Hippeastrum Herb.
Variety denomination: The amaryllis plant claimed is of the variety denominated ‘Miami’, Hippeastrum Herb.
BACKGROUND OF THE INVENTION
The present invention is a new and distinct interspecific hybrid of Hippeastrum Herb., commonly known as amaryllis, a member of the family Amaryllidaceae, and is henceforth referred to by the cultivar name ‘Miami’.
‘Miami’ originated as a cross made by the inventor in 2004 as part of a breeding program in Miami, Fla., USA. The objectives of the breeding program are to develop new amaryllis varieties with novel floral form and coloration and heat tolerance. The female parent is Hippeastrum ‘Mount Blanc’×[(H. ambiguum×H. papilio)×H. ‘Bouquet’] labeled with the breeder's code 609-04-1. The pollen parent is a proprietary selection of the cross [(Hippeastrum ambiguum×H. papilio)×H. brasilianum]בWonderland’ named ‘Orlando’.
The new cultivar was selected on the basis of its intense orange red color contrasted by a broad median white stripe on the tepals. Over the course of five years of evaluation, ‘Miami’ has shown excellent heat resistance, grown under ambient conditions in Miami, Fla. under 50% shade, and resistance to Red Scorch fungus (Staganospora curtisii).
Asexual reproduction of the new cultivar by twin-scale cuttings taken in a controlled environment in Miami, Fla. has shown that the unique features of this new amaryllis are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Miami’. It is contrasted with its parents in Table 1. This characteristic distinguishes ‘Miami’ as a new and distinct cultivar:
    • 1) Unique bright red-orange, RHS 33A and white RHS 155D, coloration pattern that has not been seen in currently available commercial cultivars.
    • 2) Additionally, ‘Miami’ shows resistance to Red Scorch fungus (Staganospora curtisii) and high temperatures, approximately 30-35° C., as do its parents.

FIGS. 2 and 3 are photographs of the flower of Hippeastrum hybrid ‘Miami’.
 DETAILED BOTANICAL DESCRIPTION
The cultivar Miami has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
Color descriptions below are based on evaluations with a Minolta CR-400 colorimeter at CIE D65/20 illumination/viewer conditions. The color parameters correspond to the uniform color space CIELAB, derived from Gonnet (Journal of Horticultural Science, Volume 68, 499-510, 1993; Food Chemistry, Volume 63, 409-415, 1998). Two color coordinates, a* and b*, as well as a psychometric index of lightness, L*, are defined. The L* is a measurement of luminosity, i.e., the equivalence of each color on the gray scale, ranging from 0 (black) to 100 (white). The a* takes positive values (0 to +60) for reddish colors and negative values (0 to −60) for the greenish ones, whereas the b* takes positive values (0 to +60) for yellowish colors and negative values (0 to −60) for the bluish ones. This is much more precise and repeatable analysis of color than obtained by using color charts (Ayala-Silva and Meerow, Proc. Intl. Trop. Hort. Soc., Volume 50, 138-144, 2006). The colorimeter takes three consecutive measurements of each sample, which was repeated three times, thus each set of color coordinates obtained are means of nine measurements. Where a reasonably close match could be discerned, The R.H.S. Colour Chart (Royal Horticultural Society, London, England, 1966) is also referenced.
