plant named ‘Fubuki’

Abstract

A Hakonechloa variety particularly distinguished by unique white and green striped foliage and a small and compact growth habit when compared to other varieties of the species, is disclosed.

Description

Genus and species: Hakonechloa macra.

Variety denomination: ‘Fubuki’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Hakonechloa, botanically known as Hakonechloa macra, a variety of the Japanese forest grass, and hereinafter referred to by the variety name ‘Fubuki’. The new variety originated from a whole plant mutation of the Hakonechloa macra parent ‘Aureola’ (unpatented) in a nursery in Porter, Wash. in September 2008.

The new variety was first propagated in September 2008, and has been asexually reproduced repeatedly by in vitro propagation for at least nine generations in Porter, Wash. The present invention has been found to retain its distinctive characteristics through successive asexual propagations by in vitro propagation.

‘Fubuki’ has not been made publicly available or sold more than one year prior to filing of this application.

SUMMARY OF THE INVENTION

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

• • 1. Unique white and green striped foliage; and
  • 2. A small and compact growth habit when compared to other varieties of the species.

DESCRIPTION OF THE PHOTOGRAPHS

This new Hakonechloa plant is illustrated by the accompanying photographs which show overall plant habit and foliage of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photos are of 9-month-old plants grown outdoors in a poly-covered greenhouse with a 50% shade cloth in 10.0 cm containers in Porter, Wash. in late summer/early autumn.

FIG. 1 shows a view of the foliage from above the plant.

FIG. 2 shows the whole plant, including the foliage and habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Fubuki’. The data which define these characteristics were collected from asexual reproductions carried out in Porter, Wash. The plant history was taken on 9-month-old plants grown in 10.0 cm containers outdoors in a poly-covered greenhouse with 50% shade cloth in late summer/early autumn. Color references were taken under natural light and are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (1995).

    • Surface texture.—Smooth (not pubescent).
    • Internode length.—Internodes are 2.0 cm apart on the basal portion of the culm, shortening to 1.0 cm towards the expanding tip of the culm.
• Foliage (leaf) description:
  • • Number (per stem).—10 leaves per 16.0 cm culm, 7 leaves per 11.0 cm culm.

    • Color.—Leaves have bi-colored striation, dark-green and creamy-white multiple stripes per leaf, most often with a dark-green margin, but occasionally a creamy-white margin. Upper and lower surfaces: RHS 139A (Dark-green) stripes interspersed with RHS 155A (White) stripes. The number of stripes can vary; a typical leaf has 8 dark-green stripes with 7 white stripes.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETYS

‘Fubuki’ differs from the parent ‘Aureola’ (unpatented) in that ‘Fubuki’ has white and green striped foliage, while ‘Aureola’ has gold and green striped foliage. Additionally, ‘Fubuki’ has a more compact growth habit that ‘Aureola’.

‘Fubuki’ differs from the commercial comparison variety ‘Nicolas’ (U.S. Plant Pat. No. 19,898) in that ‘Fubuki’ has white and green striped foliage, while ‘Nicolas’ has green to yellow-green non-striped foliage.
