USPP27435P2 - Pennisetum plant named ‘JS Jommenik’ - Google Patents

Abstract

A new Pennisetum plant particularly distinguished by having a compact growth habit, green-yellow to yellow foliage, and a bushy, semi-globular plant shape, is disclosed.

Description

Genus and species: Pennisetum alopecuroides.

Variety denomination: ‘JS Jommenik’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Pennisetum, botanically known as Pennisetum alopecuroides and hereinafter referred to by the variety name ‘JS Jommenik’. ‘JS Jommenik’ was discovered as a branch (shoot) mutation in Pennisetum alopecuroides ‘Gelbstiel’ (unpatented) in summer 2007 in the nursery of the inventor in Buggenhout, Belgium.

‘JS Jommenik’ was first propagated through division in summer 2009 in summer 2007 in the nursery of the inventor in Buggenhout, Belgium. ‘JS Jommenik’ was found to reproduce true to type in successive generations of asexual propagation via tissue culture and division in Buggenhout, Belgium.

A Community Plant Variety Rights application has been filed with the Community Plant Variety Office on Sep. 9, 2014, File No. 2014/2194.

SUMMARY

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

• • 1. A compact growth habit;
  • 2. Green-yellow to yellow foliage; and
  • 3. A bushy, semi-globular plant shape.

DESCRIPTION OF THE PHOTOGRAPHS

This new Pennisetum plant is illustrated by the accompanying photographs which show a whole plant view and a close-up view of the foliage. The photographs are of a plant approximately two-years-old grown outdoors in Buggenhout, Belgium. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows an overall view of multiple plants in rows grown outside.

FIG. 2 shows a close-up of the foliage of the plant.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘JS Jommenik’. The data which define these characteristics were collected from asexual reproductions carried out in Buggenhout, Belgium. Data was collected on two-year-old plants in November 2015. Observations were taken indoor, and next to a north-facing clear-glass window where the average day temperatures were approximately 7° C. to 18° C. and where the average night temperatures were approximately −1° C. to 12° C. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 6^th edition (2015).
