plant named ‘ANTHHOZIF’

Abstract

A new Anthurium plant rich in shooting and number of spathes named ‘ANTHHOZIF’ particularly distinguished by having weakly blistered and weakly glossy, white, long ovate, and durable spathes that retain the original color for a very long period of time and are positioned far above the leaves, with dark green, long ovate, durable leaves, white spadices with yellow tips, early and rich flowering continuously throughout the year, and a plant height of 36.0 cm to 46.0 cm is disclosed.

Description

Genus and species: Anthurium andraeanum L.

Variety denomination:

‘ANTHHOZIF’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andraeanum L., and hereinafter referred to by the variety name ‘ANTHHOZIF’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new plant with a height of 36.0 cm to 46.0 cm having weakly blistered and weakly glossy, white, long ovate, and durable spathes.

The new variety originated from a cross-pollination made in September 2013 in Bleiswijk, the Netherlands. The female parent was a pink Anthurium pot plant designated ‘22570-02’ (unpatented), and the male parent was a pink Anthurium pot plant designated ‘26116-02’ (unpatented).

A single plant was selected from the progeny of the stated cross in August 2015. Asexual reproduction of the new variety by tissue culture in 2017 in Bleiswijk, the Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Community Plant Variety Rights for this variety have been applied for in the European Union on Nov. 12, 2019 (Application no. 2019/2945), by Applicant who obtained the subject matter disclosed directly from the inventor. ‘ANTHHOZIF’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application with the exception of sales or disclosures made one year or less before the effective filing date of this claimed invention by Applicant who obtained ‘ANTHHOZIF’ directly from the inventor.

SUMMARY OF THE INVENTION

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

• • 1) Weakly blistered and weakly glossy, white, long ovate spathes;
  • 2) White spadices with yellow tips;
  • 3) Green, long ovate leaves;
  • 4) Plant is rich in shoots and number of spathes; and
  • 5) Spathes are positioned far above the leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds, 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 34-week-old plant grown in a greenhouse in Bleiswijk, the Netherlands, in November 2021. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHHOZIF’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, the Netherlands. The plant history was taken on 34-week-old plants which were planted from tissue culture in 12-centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November 2021. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (RHS) (2015).
