Botanical classification: Hibiscus acetosella.
Cultivar denomination: ‘Maple Sugar’.
The present invention relates to a new and distinct cultivar of Hibiscus, botanically known as Hibiscus acetosella, and hereinafter referred to by the name ‘Maple Sugar’.
The new Hibiscus is a product of a planned breeding program conducted by the Inventor in Portland, Oreg. The objective of the breeding program is to create new Hibiscus cultivars with attractive leaf and flower coloration.
The new Hibiscus originated from a cross-pollination made by the Inventor in Mexico in October, 2000, of two unnamed selections of Hibiscus acetosella, not patented. The cultivar Maple Sugar was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Mexico in November, 2000.
Asexual reproduction of the new Hibiscus by vegetative cuttings in a controlled environment in Portland, Oreg. since December, 2000, has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.
The cultivar Maple Sugar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature 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 ‘Maple Sugar’. These characteristics in combination distinguish ‘Maple Sugar’ as a new and distinct cultivar:
Compared to plants of the parent selections, plants of the new Hibiscus have slightly larger leaves and more intense leaf and flower colors.
Compared to plants of the other selections and cultivars of Hibiscus acetosella known to the Inventor, plants of the new Hibiscus have slightly larger leaves and more intense leaf and flower colors.
The accompanying colored photographs illustrate the overall appearance of the new Hibiscus, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hibiscus.
The photographs at the top left and right of the sheet comprise front and side perspective views of typical flowers of ‘Maple Sugar’.
The photograph at the center of the sheet is a close-up view of typical flowers of ‘Maple Sugar’ with the corolla removed.
The photograph at the bottom of the sheet comprises a side perspective view of a typical plant of ‘Maple Sugar’.
The aforementioned photographs and following observations, measurements and values describe plants grown in an outdoor nursery in Bonsall, Calif. during the late spring under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 18° C. to 38° C. and night temperatures ranged from 13° C. to 18° C. Plants were about seven to eight weeks old when the photographs and the description were taken. Plants were pinched two times. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
