USPP17416P2 - Hibiscus plant named ‘Bricutts’ - Google Patents

Abstract

A new and distinct cultivar of Hibiscus plant named ‘Bricutts’, characterized by its upright plant habit; freely branching habit; dense and bushy growth habit; and numerous, large, semi-double and white-colored flowers with red purple-colored centers and basal venation and numerous stamenoid petaloids.

Description

Botanical designation: Hibiscus syriacus.

Cultivar denomination: ‘Bricutts’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hibiscus plant, botanically known as Hibiscus syriacus, and hereinafter referred to by the cultivar name Bricutts.

The new Hibiscus is a naturally-occurring branch mutation of the Hibiscus syriacus cultivar Notwoodone, disclosed in U.S. Plant Pat. No. 12,619. The new Hibiscus was discovered and selected by the Inventor in a controlled environment in St. Barthelemy D'Anjou, France in July, 2001. The new Hibiscus was selected on the basis of its flower coloration.

Asexual reproduction of the new Hibiscus by cuttings at St. Barthelemy D'Anjou, France, since July, 2001 has shown that the unique features of this new Hibiscus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Bricutts have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bricutts’. These characteristics in combination distinguish ‘Bricutts’ as a new and distinct Hibiscus cultivar:

• • 1. Upright plant habit.
  • 2. When pinched, very freely branching habit; dense and bushy appearance.
  • 3. Numerous, large, semi-double and white-colored flowers with red purple-colored centers and basal venation and numerous stamenoid petaloids.

Plants of the new Hibiscus differ primarily from plants of the parent, the cultivar Notwoodone, in flower color as plants of the cultivar Notwoodone have lavender-colored flowers.

Plants of the new Hibiscus can be compared to plants of the Hibiscus cultivar Notwoodtwo, disclosed in U.S. Plant Pat. No. 12,612. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Hibiscus differed from plants of the cultivar Notwoodtwo in the following characteristics:

• • 1. Plants of the new Hibiscus were smaller than plants of the cultivar Notwoodtwo.
  • 2. Plants of the new Hibiscus and the cultivar Notwoodtwo differed in flower color as plants of the cultivar Notwoodtwo had pure white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Hibiscus.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Bricutts’ grown in a outdoor nursery.

The photograph at the top of the sheet comprises a close-up view of a typical flower of ‘Bricutts’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
