1. A new and distinct variety of Hosta plant named ‘Color Festival’ as shown and described herein.

Description:

Genus and species: Hosta sp.

Variety denomination: ‘Color Festival’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Hosta, botanically known as Hosta sp. and hereinafter referred to by the variety name ‘Color Festival’. The new variety originated in July 2007 in Deinze, Belgium, from a naturally-occurring whole-plant mutation of the parent Hosta plant ‘Enterprise’ (unpatented).

The new variety was first propagated in October 2008 in Rijswijk, The Netherlands via in-vitro propagation, and has been asexually reproduced by in-vitro propagation using meristem tissue culture in Rijswijk, The Netherlands for at least 2 generations. The present invention has been found to retain its distinctive characteristics through successive asexual propagation via in-vitro propagation.

Plant Breeder's Rights for this variety have been applied for in the European Union on Dec. 2, 2009. ‘Color Festival’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

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

    • 1. Fluorescent yellow-green streaks between dark green margins; and
    • 2. A light yellow-green central blotch in immature leaves and a yellow central blotch in mature leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Hosta plant is illustrated by the accompanying photographs which show the foliage and habit of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 6-month old Hosta plant grown in a greenhouse in Noordwijkerhout, The Netherlands.

FIG. 1 shows the overall plant habit and foliage.

FIG. 2 shows a close-up of a mature leaf.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘Color Festival’. The data which define these characteristics were collected from asexual reproductions carried out in Noordwijkerhout, The Netherlands. The plant history was taken in October 2009 on 6-month old plants grown in 11 cm and larger pots in a glass greenhouse or field grown, in daytime temperatures between 15° C. and 27° C. and nighttime temperatures between 10° C. and 18° C. No growth retardants, photoperiodic treatments, or other cultural or environmental treatments or conditions were used. Observations of the plants were made at a normal light level. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘Color Festival’ differs from the parent Hosta sp. variety ‘Enterprise’ (unpatented), in that ‘Color Festival’ has a light yellow-green central blotch in immature leaves and conspicuous fluorescent yellow-green streaks between the dark green margins and a yellow central blotch in mature leaves, whereas ‘Enterprise’ has a white central blotch in immature leaves and no streaks between the margins and the central blotch in mature leaves.

‘Color Festival’ differs from the commercial Hosta sp. variety ‘Captain Kirk’ (unpatented), in that ‘Color Festival’ has a light yellow-green central blotch in immature leaves and conspicuous fluorescent yellow-green streaks between the dark green margins and a yellow central blotch in mature leaves, whereas ‘Captain Kirk’ has a yellow central blotch in immature leaves and no streaks between the margin and the central blotch in mature leaves.
