Abstract

A new and distinct cultivar of Cytisus plant named ‘SMCSAPY’, characterized by its upright to outwardly arching plant habit; vigorous growth habit; freely branching habit; freely flowering habit; large red purple and yellow-colored flowers; and good garden performance.

Description

Botanical designation: Cytisus scoparius.
Cultivar denomination: ‘SMCSAPY’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Cytisus plant, botanically known as Cytisus scoparius, commonly referred to as Scotch Broom and hereinafter referred to by the name ‘SMCSAPY’.
The new Cytisus plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to create new uniform Cytisus plants with attractive flower form and color.
The new Cytisus plant originated from an open-pollination in 2009 in Grand Haven, Mich. of an unnamed selection of Cytisus scoparius, not patented, as the female, or seed, parent with an unknown selection of Cytisus scoparius as the male, or pollen, parent. The new Cytisus plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich. during the spring of 2013.
Asexual reproduction of the new Cytisus plant by softwood stem cuttings in a controlled environment in Grand Haven, Mich. since the spring of 2013 has shown that the unique features of this new Cytisus plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Cytisus 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 ‘SMCSAPY’. These characteristics in combination distinguish ‘SMCSAPY’ as a new and distinct Cytisus plant:
    • 1. Upright to outwardly arching plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Large red purple and yellow-colored flowers.
    • 6. Good garden performance.
Plants of the new Cytisus can be compared to plants of the female parent selection. Plants of the new Cytisus differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Cytisus are more outwardly arching than plants of the female parent selection.
    • 2. Plants of the new Cytisus have larger flowers than plants of the female parent selection.
    • 3. Plants of the new Cytisus and the female parent selection differ in flower color as plants of the female parent selection have yellow-colored flowers.
Plants of the new Cytisus can be compared to plants of Cytisus scoparius ‘Burkwoodii’, not patented. In side-by-side comparisons, plants of the new Cytisus differ from plants of ‘Burkwoodii’ in the following characteristics:
    • 1. Plants of the new Cytisus are not as compact as plants of ‘Burkwoodii’.
    • 2. Plants of the new Cytisus are more outwardly arching than plants of ‘Burkwoodii’.
    • 3. Plants of the new Cytisus are more freely branching than plants of ‘Burkwoodii’.
    • 4. Plants of the new Cytisus have red purple and yellow- colored flowers whereas plants of ‘Burkwoodii’ have faded red and yellow-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Cytisus 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 Cytisus plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘SMCSAPY’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘SMCSAPY’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in three-gallon containers during the spring in a polyethylene-covered greenhouse in Grand Haven, Mich. and under cultural practices typical of commercial Cytisus production. Plants were two years old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 5° C. to 10° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
