plant named ‘Bokrammi’

Abstract

A new and distinct cultivar of Rose plant named ‘Bokrammi’, characterized by its upright and mounding plant habit; dark green-colored foliage; freely branching growth habit; freely flowering habit; red purple-colored flowers; large glossy red-colored fruits; and good garden performance.

Description

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Bokrammi’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Rose plant, botanically known as Rosa hybrida, commercially used as an ornamental shrub, and hereinafter referred to by the name ‘Bokrammi’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Boskoop, The Netherlands. The objective of the breeding program was to develop new uniform shrub Rose varieties with attractive flower and fruit coloration.

The new Rose plant originated from a cross-pollination made by the Inventor during the summer of 1996 of two unnamed seedling selections of Rosa hybrida, not patented. The new Rose plant was discovered and selected by the Inventor during the summer of 2001 as a single flowering plant within the progeny of the stated cross-pollination in a controlled outdoor nursery environment in Boskoop, The Netherlands.

Asexual reproduction of the new Rose plant by softwood cuttings in a controlled greenhouse environment in Boskoop, The Netherlands since the summer of 2001, has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

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

• • 1. Upright and mounding plant habit.
  • 2. Dark green-colored foliage.
  • 3. Freely branching growth habit.
  • 4. Freely flowering habit.
  • 5. Red purple-colored flowers.
  • 6. Large glossy red-colored fruits.
  • 7. Good garden performance.

Plants of the new Rose differ from plants of the female parent selection primarily in plant size as plants of the new Rose are shorter than plants of the female parent selection.

Plants of the new Rose differ from plants of the male parent selection primarily in flowering habit as plants of the new Rose are more freely flowering than plants of the male parent selection.

Plants of the new Rose can be compared to plants of the Rosa hybrida ‘Meipopul’, disclosed in U.S. Plant Pat. No. 9,777. Plants of the new Rose differ from plants of ‘Meipopul’ in the following characteristics:

• • 1. Plants of the new Rose are more freely flowering than plants of ‘Meipopul’.
  • 2. Fruits of plants of the new Rose are glossier than fruits of plants of ‘Meipopul’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Rose plant, 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 Rose.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering and fruiting plant of ‘Bokrammi’ ground in an outdoor nursery.

The photograph at the top of the sheet is a close-up view of typical flowers of ‘Bokrammi’.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs, following observations and measurements describe plants grown during the summer in Boskoop, The Netherlands, in an outdoor nursery and under commercial production practices. During the production of the plants, day temperatures ranged from 14° C. to 32° C. and night temperatures ranged from 7° C. to 14° C. Plants had been growing for years when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
