plant named ‘Hamcoec’

Abstract

A new cultivar of Cosmos plant named ‘Hamcoec’ that is characterized by large diameter red-brown inflorescences with yellow pollen, large ray florets and long peduncles.

Description

Botanical classification: Cosmos hybrida.

Variety denomination: ‘Hamcoec’.

CROSS-REFERENCE TO RELATED AND CO-PENDING APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. 119(f) of the application for a grant of New Zealand Plant Breeders Rights which was filed for the instant plant variety on Sep. 17, 2013, Application Number 31608.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cosmos plant botanically known as Cosmos hybrida and hereinafter referred to by the cultivar name ‘Hamcoec’.

‘Hamcoec’ originated from open pollination of the female or seed parent plant an unidentified proprietary Cosmos atrosanguineus (not patented). The male or pollen parent plant is unknown. The resulting seeds were subsequently harvested and grown. ‘Hamcoec’ was selected as a single plant from within the stated progeny in a controlled environment in Auckland, New Zealand in 2009.

Asexual reproduction of the new cultivar ‘Hamcoec’ first occurred by tissue culture in 2009 in Auckland, New Zealand. 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 Cosmos cultivar ‘Hamcoec’. These traits in combination distinguish ‘Hamcoec’ as a new and distinct cultivar apart from other existing known varieties of Cosmos.

• • 1. Cosmos ‘Hamcoec’ exhibits large diameter red-brown inflorescences with yellow pollen.
  • 2. Cosmos ‘Hamcoec’ exhibits inflorescences having large ray florets.
  • 3. Cosmos ‘Hamcoec’ exhibits long peduncles.
    The closest comparison cultivar is Cosmos ‘Coco Mocha’ (not patented). ‘Hamcoec’ is distinguishable from ‘Coco Mocha’ by the following characteristics:
  • 1. ‘Hamcoec’ exhibits leaves that have fewer divisions than the leaves of ‘Coco Mocha’.
  • 2. ‘Hamcoec’ exhibits larger diameter inflorescences than the inflorescences of ‘Coco Mocha’.
  • 3. ‘Hamcoec’ exhibits longer peduncles than the peduncles of ‘Coco Mocha’.
  • 4. ‘Hamcoec’ exhibits longer, broader and flatter ray florets than the ray florets of ‘Coco Mocha’. The ray florets of ‘Coco Mocha’ are smaller and incurved.

In comparison to the female or seed parent plant. an unidentified proprietary Cosmos atrosanguineus, ‘Hamcoec’ is distinguishable by the following characteristics:

• • 1. ‘Hamcoec’ exhibits darker color red-brown inflorescences than the inflorescences of the seed parent plant.
  • 2. ‘Hamcoec’ exhibits smaller diameter inflorescences than the inflorescences of the seed parent plant.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Cosmos ‘Hamcoec’. The plants in the photograph show an overall view of a 3 month old plant grown outdoors in Auckland, New Zealand.

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 Cosmos cultivar named ‘Hamcoec’. Data was collected in Auckland, New Zealand from 3 month old outdoor grown plants. The time of year was Summer in the Southern Hemisphere and the temperature range was 18-25 degrees Centigrade during the day and 6-12 degrees Centigrade at night. The light level was natural outdoor light. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Hamcoec’ 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.
