plant named ‘Spitenz Dark’

Abstract

A Celosia plant named ‘Spitenz Dark’ characterized by its many dark purple colored spikes, prolific branching, foliage from the bottom to the top of the plant, a compact and symmetrical plant habit, and a response time of approximately 7.5 weeks is disclosed.

Description

Genus and species: Celosia argentea.

Variety denomination: ‘Spitenz Dark’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Celosia plant, botanically known as Celosia argentea, and hereinafter referred to by the variety name ‘Spitenz Dark’. This new variety produces many medium sized spikes with dark purple colored individual blooms and a blooming period of about eight weeks.

The new variety ‘Spitenz Dark’ is a naturally occurring sport from the unpatented Celosia variety ‘Innovo’. The new and distinct variety was discovered and selected as a single plant in a greenhouse in Monster, The Netherlands in May 2013.

The new variety ‘Spitenz Dark’ was first asexually reproduced by terminal vegetative cuttings in a greenhouse in Monster, The Netherlands in August 2013 and has been asexually reproduced for one and a half years. The new variety ‘Spitenz Dark’ has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new variety when grown under normal horticultural practices in Monster, The Netherlands.

• • 1. Dark purple spiked-type inflorescences having an abundance of spikes on each branch;
  • 2. Prolific branching;
  • 3. Compact symmetrical plant habit; and
  • 4. Foliage located all over the stem to the bottom of the plant.

COMPARISON WITH THE PARENT VARIETY

The new variety ‘Spitenz Dark’ differs from parent variety in having a darker flower color.

COMPARISON WITH COMMERCIAL VARIETIES

The new variety ‘Spitenz Dark’ differs from the commercial Celosia ‘Spitenz’ U.S. Plant Pat. No. 23,076 in that ‘Spitenz Dark’ is a more compact plant. Further, the new variety ‘Spitenz Dark’ has a darker flower color and has broader and shorter spikes than ‘Spitenz’. The new variety ‘Spitenz Dark’ has foliage that is narrower and slightly smaller than that of ‘Spitenz’ and a flowering response time that is approximately one week longer than the response time of ‘Spitenz’.

The new variety ‘Spitenz Dark’ can also be compared to Celosia ‘Spitenz Lipstick’ patent pending, filed concurrently having application Ser. No. 14/999,491. ‘Spitenz Dark’ produces darker colored flowers. Further, the new variety ‘Spitenz Dark’ has shorter flowering spikes on average than ‘Spitenz Lipstick’. The new variety ‘Spitenz Dark’ produces less flowering spikes per plant than ‘Spitenz Lipstick’. Peduncles and stems of ‘Spitenz Dark’ are colored near yellow-Green 146C, compared to Red-Purple 58A appearing on ‘Spitenz Lipstick’.

DESCRIPTION OF THE PHOTOGRAPHS

This new Celosia plant is illustrated by the accompanying photographs which show blooms and foliage of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a plant that has been in bloom for approximately 3 weeks.

FIG. 1 shows the plant habit including the foliage and inflorescences of the new variety.

FIG. 2 is a close-up of the new variety ‘Spitenz Dark’, showing individual spikes and inflorescences per branch.

FIG. 3 is a close-up of the upper and under surfaces of the leaves of the new variety ‘Spitenz Dark’.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Spitenz Dark’. The data which define these characteristics were collected from asexual reproductions carried out in Monster, The Netherlands. The plant history was taken on un-pinched plants of 8 to 10 weeks old, which were grown in 10 cm pots in a greenhouse in Monster, The Netherlands under controlled day length and temperatures. Growth retardants were used weekly. The color readings were determined under natural light. Color references are to The R.H.S.
