USPP35932P2 - Allium plant named ‘FB2020’ - Google Patents

Abstract

A new and distinct Allium cultivar named ‘FB2020’ is disclosed, characterized by foliage having a grey-green glaucous layer. Flowers are purple. The new variety is an Allium, typically produced as an outdoor ornamental plant.

Description

Latin name of the genus and species: Allium nutans.

Variety denomination: ‘FB2020’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new variety originated as a naturally occurring whole plant mutation of the unpatented ‘Cobalt Millennium’ variety of Allium. The new variety was selected by the inventor, during February of 2017, at a commercial nursery in Victoria, Australia.

Asexual reproduction of the new cultivar ‘FB2020’ was first performed by division in Victoria, Australia in February of 2017. The new variety was maintained as a separate clone and tested for performance and stability over 5 generations. During the evaluation period, access to all plants was restricted, as plants were kept in a location not open to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

Date of first sale was Oct. 31, 2022, in Australia. This sale was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made between Oct. 31, 2022 and the filing of this application fall within the exception allowed under 102(b)(1).

SUMMARY OF THE INVENTION

The cultivar ‘FB2020’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘FB2020’. These characteristics in combination distinguish ‘FB2020’ as a new and distinct Allium cultivar:

• • 1. Grey-green glaucous foliage.
  • 2. Purple flowers.

PARENT COMPARISON

Plants of the new cultivar ‘FB2020’ are similar to the parent, Allium ‘Millenium Cobalt’ in most horticultural characteristics. The new variety, however, differs in the following ways:

• • 1. The new variety produces grey-green glaucous foliage, compared to the green foliage of parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘FB2020’ are similar to the commercial variety Allium ‘Pink Pepper’, unpatented, in most horticultural characteristics. The new variety, however, differs in the following:

• • 1. ‘FB2020’ has a purple flower; flowers of ‘Pink Pepper’ are pink.
  • 2. ‘FB2020’ has grey/green foliage; foliage of ‘Pink Pepper’ is green.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plants of ‘FB2020’ at approximately 22 months old from a rooted cutting grown in Victoria, Australia.

FIG. 2 illustrates in full color a close up of the flowers of ‘FB2020’.

The photographs were 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.
