plant named ‘EC-SENEC-1810’

Abstract

A new cultivar of Senecio plant named ‘EC-SENEC-1810’ that is characterized by heart shaped leaves that have a bi-colored pattern of silver-grey and green on the upper surface and are purple in color on the lower surface.

Description

Botanical classification: Senecio mikanioides.

Variety denomination: ‘EC-SENEC-1810’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Senecio plant botanically known as Senecio mikanioides and hereinafter referred to by the cultivar name ‘EC-SENEC-1810’.

‘EC-SENEC-1810’ originated from the crossing of the female or seed parent, an unnamed Senecio mikanioides cultivar and the male or pollen parent, an unnamed Senecio mikanioides cultivar. The crossing was conducted in 2014 in Sappemeer, Netherlands. The resulting seeds were subsequently planted and grown. The cultivar ‘EC-SENEC-1810’ was selected by the inventor in 2015 in a controlled environment as a single plant within the progeny of the stated cross in a cultivated area of Sappemeer, Netherlands.

Asexual reproduction of the new cultivar ‘EC-SENEC-1810’ first occurred by stem cuttings in 2015 in Sappemeer, Netherlands. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Senecio cultivar ‘EC-SENEC-1810’. These traits in combination distinguish ‘EC-SENEC-1810’ as a new and distinct cultivar apart from other existing varieties of Senecio known by the inventor.

• • 1. Senecio ‘EC-SENEC-1810’ exhibits leaves having a bi-colored pattern of silver-grey and green on the upper surface.
  • 2. Senecio ‘EC-SENEC-1810’ exhibits leaves having a purple color on the lower surface.
  • 3. Senecio ‘EC-SENEC-1810’ exhibits heart shaped leaves.

The closest comparison cultivars are plants of the species Senecio mikanioides (not patented) and plants of the species Senecio macroglossus (not patented). ‘EC-SENEC-1810’ is distinguishable from Senecio mikanioides by the following characteristics:

• • 1. Senecio ‘EC-SENEC-1810’ exhibits leaves having a bi-colored pattern of silver-grey and green on the upper surface. In comparison, the leaves of Senecio mikanioides are entirely green on the upper surface.

‘EC-SENEC-1810’ is distinguishable from Senecio macroglossus by the following characteristics:

• • 1. Senecio ‘EC-SENEC-1810’ exhibits leaves having a bi-colored pattern of silver-grey and green on the upper surface. In comparison, the leaves of Senecio macroglossus are green with a white and green vein pattern on the upper surface.
  • 2. The leaves of Senecio ‘EC-SENEC-1810’ are heart shaped. In comparison, the leaves of Senecio macroglossus are arrow shaped.

‘EC-SENEC-1810’ is distinguishable from the female parent plant, by the following characteristics:

• • 1. The internodes of ‘EC-SENEC-1810’ are shorter than the internodes of the female parent plant.
  • 2. ‘EC-SENEC-1810’ has a more compact habit than the habit of the female parent plant.

‘EC-SENEC-1810’ is distinguishable from the male parent plant by the following characteristics:

• • 1. The internodes of ‘EC-SENEC-1810’ are shorter than the internodes of the male parent plant.
  • 2. ‘EC-SENEC-1810’ has a more compact habit than the habit of the male parent plant.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Senecio ‘EC-SENEC-1810’. The photograph shows an overall view of a 40 week old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance, it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Senecio cultivar named ‘EC-SENEC-1810’. Data was collected in Sappemeer, Netherlands from 40 week old plants grown in a glass greenhouse in 15.0 cm. diameter containers. The time of year was Fall and the temperature range was 18-24 degrees Centigrade during the day and 18-21 degrees Centigrade at night. The light level was natural light level. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2015 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘EC-SENEC-1810’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
