Abstract

A new and distinct cultivar of Senecio plant named ‘SI SEN 1005’, characterized by its uniform, upright and bushy plant habit; flat obovate leaves; medium green-colored leaves covered with a greyed green-colored cuticle with distinct pale green-colored venation; and excellent interiorscape performance.

Description

Botanical designation: Senecio cephalophorus x Senecio fulgens.
Cultivar denomination: ‘SI SEN 1005’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Senecio plant, botanically known as Senecio cephalophorus x Senecio fulgens, and hereinafter referred to by the name ‘SI SEN 1005’.
The new Senecio plant is a product of a planned breeding program conducted by the Inventor in Krimpen aan den IJssel, The Netherlands. The objective of the breeding program was to develop new and distinct Senecio plants with good interiorscape performance.
The new Senecio plant originated from a cross-pollination made by the Inventor in 2012 of Senecio cephalophorus ‘Mountain Fire’, not patented, as the female, or seed, parent with Senecio fulgens ‘Mandarin’, not patented, as the male, or pollen, parent. The new Senecio plant was discovered and selected as a single plant within the progeny of the stated cross-pollination in a controlled environment in Krimpen aan den IJssel, The Netherlands.
Asexual reproduction of the new Senecio plant by tip cuttings in a controlled environment in Krimpen aan den IJssel, The Netherlands since March, 2014 has shown that the unique features of this new Senecio plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Senecio 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 ‘SI SEN 1005’. These characteristics in combination distinguish ‘SI SEN 1005’ as a new and distinct Senecio plant:
    • 1. Uniform, upright and bushy plant habit.
    • 2. Flat obovate leaves.
    • 3. Medium green-colored leaves covered with a greyed green-colored cuticle with distinct pale green-colored venation.
    • 4. Excellent interiorscape performance.
Plants of the new Senecio differ primarily from plants of the female parent, ‘Mountain Fire’, in leaf color as plants of ‘Mountain Fire’ have grey green-colored leaves without distinct venation.
Plants of the new Senecio differ primarily from plants of the male parent, ‘Mandarin’, in the following characteristics:
    • 1. Plants of the new Senecio are more freely branching and bushier than plants of ‘Mandarin’.
    • 2. Leaves of plants of the new Senecio are not as round as leaves of plants of ‘Mandarin’.
    • 3. Plants of the new Senecio and ‘Mandarin’ differ in leaf color as leaves of plants of ‘Mandarin’ are pale green in color with grey-colored venation.
Plants of the new Senecio can be compared to plants of Senecio cephalophorus ‘Tanzanite’, not patented. In side-by-side comparisons, plants of the new Senecio differ primarily from plants of ‘Tanzanite’ in leaf color as plants of ‘Tanzanite’ have grey green-colored leaves without distinct venation.
Plants of the new Senecio can also be compared to plants of Senecio cephalophorus ‘Fuji’, not patented. In side-by-side comparisons, plants of the new Senecio differ primarily from plants of ‘Fuji’ in the following characteristics:
    • 1. Plants of the new Senecio are more freely branching and bushier than plants of ‘Fuji’.
    • 2. Plants of the new Senecio and ‘Fuji’ differ in leaf color as leaves of plants of ‘Fuji’ are pale green in color without distinct venation.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Senecio 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 Senecio plant.
The photograph on the first sheet comprises a top perspective view of a typical plant of ‘SI SEN 1005’ grown in a container.
The photograph on the second sheet is a close-up view of a typical plant of ‘SI SEN 1005’ grown in a container.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the winter in 10.5-cm containers in a glass-covered greenhouse in Krimpen aan den IJssel, The Netherlands and under cultural practices typical of commercial Echeveria production. During the production of the plants, day temperatures ranged from 18° to 25° C. and night temperatures ranged from 15° to 18° C. Plants were 30 weeks old when the photographs and description were taken. 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.
