plant named ‘BARSOLMAG’

Abstract

A new and distinct cultivar of Solidago plant named ‘BARSOLMAG’, characterized by its upright plant habit; freely branching growth habit; early and freely flowering habit; unique flat-top spray formation; and inflorescences with light yellow-colored ray florets.

Description

Botanical designation: Solidago hybrida.

Cultivar denomination: ‘BARSOLMAG’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Solidago plant, botanically known as Solidago hybrida, and hereinafter referred to by the name ‘BARSOLMAG’.

The new Solidago plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the program is to create and develop new Solidago plants with attractive inflorescences.

The new Solidago originated from a cross-pollination made by the Inventor on Jun. 1, 2009 of a proprietary selection of Solidago hybrida identified as code number SO-0007, not patented, as the female, or seed, parent with a proprietary selection of Solidago hybrida identified as code number SO08-000042-020, not patented, as the male, or pollen, parent. The new Solidago plant 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 Aalsmeer, The Netherlands on Jun. 1, 2010.

Asexual reproduction of the new Solidago plant by vegetative terminal cuttings in a controlled environment in Aalsmeer, The Netherlands since Jan. 1, 2012, has shown that the unique features of this new Solidago plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Solidago have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘BARSOLMAG’. These characteristics in combination distinguish ‘BARSOLMAG’ as a new and distinct Solidago plant:

• • 1. Upright plant habit.
  • 2. Freely branching growth habit.
  • 3. Early and freely flowering habit.
  • 4. Unique flat-top spray formation.
  • 5. Inflorescences with light yellow-colored ray florets.

Plants of the new Solidago differ from plants of the female parent selection in the following characteristics:

• • 1. Sprays of plants of the new Solidago are flat-top in shape whereas sprays of plants of the female parent selection are plume-shaped.
  • 2. Inflorescences of plants of the new Solidago are slightly larger than inflorescences of plants of the female parent selection.

Plants of the new Solidago differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Solidago are taller than plants of the male parent selection.
  • 2. Sprays of plants of the new Solidago are flatter in shape than sprays of plants of the male parent selection.

Plants of the new Solidago can be compared to plants of Solidago hybrida ‘Bareight’, disclosed in U.S. Plant Pat. No. 12,525. In side-by-side comparisons, plants of the new Solidago differ from plants of ‘Bareight’ in the following characteristics:

• • 1. Plants of the new Solidago have longer and thicker lateral branches than plants of ‘Bareight’.
  • 2. Inflorescences of plants of the new Solidago have more ray and disc florets than inflorescences of plants of ‘Bareight’.
  • 3. Sprays of plants of the new Solidago are flat-top in shape whereas sprays of plants of ‘Bareight’ are plume-shaped.
  • 4. Inflorescences of plants of the new Solidago are larger than inflorescences of plants of ‘Bareight’.

Plants of the new Solidago can also be compared to plants of Solidago hybrida ‘Golden Glory’, not patented. In side-by-side comparisons, plants of the new Solidago differ from plants of ‘Golden Glory’ in the following characteristics:

• • 1. Plants of the new Solidago are shorter than plants of ‘Golden Glory’.
  • 2. Sprays of plants of the new Solidago are flat-top in shape whereas sprays of plants of ‘Golden Glory’ are plume-shaped.
  • 3. Inflorescences of plants of the new Solidago are larger than inflorescences of plants of ‘Golden Glory’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Solidago plants. These photographs shows 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 Solidago plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering stem of ‘BARSOLMAG’.

The photograph on the second sheet is a close-up view of a typical flowering spray of ‘BARSOLMAG’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown in Naivasha, Kenya during the winter in ground beds in an outdoor nursery and under cultural practices which approximate those generally used in commercial Solidago production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 10° C. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were about six months old when the photographs and description were taken.
