Abstract: A new and distinct Hosta cultivar named `Ben Vernooij` is disclosed, characterized by distinctive round foliage on thick petioles, vigorous plant habit and strong foliage, with good resistance to environmental stressors and large flowers. The new variety is a Hosta, typically used for outdoor ornamental purposes.
Claim: What is claimed is:

1. A new and distinct cultivar of Hosta plant named `Ben Vernooij` as herein illustrated and described.
Description: Latinname of the genus and species: Hosta hybrid.

Variety denomination: `BEN VERNOOIJ`.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as an induced mutation using the known chemical colchicine, of Hosta hybrid `First Frost` unpatented. `Ben Vernooij` was discovered by the inventor, Marco Fransen, a citizen of the Netherlands in October of 2008,at a research facility in Ter Aar, The Netherlands. The intent of the breeding program was to create new tetraploid Hosta hyrids with strong foliage and vigorous plants.

Directly after discovery of the tetraploid mutation, the inventor initiated cultivation in tissue culture, during October of 2008, in a commercial laboratory in Iribov Heerhugowaard, the Netherlands. Subsequently `Ben Vernooij` has beenreproduced by micro-propagation in a commercial laboratory in Iribov Heerhugowaard, the Netherlands and has shown that the unique features of this cultivar are stable and reproduced true to type through several generations.

SUMMARY OF THE INVENTION

The cultivar `Ben Vernooij` 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 variancein genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Ben Vernooij` These characteristics in combination distinguish `Ben Vernooij` as a new and distinct Hosta cultivar: 1. Distinctive, roundfoliage on thick petioles 2. Thick foliage resistant to environmental stressors. 3. Vigorous plant. 4. Large flowers.

COMPARISON TO PARENT

Plants of the new cultivar `Ben Vernooij` are similar to plants of the parent; Hosta hybrid `First Frost` in most horticultural characteristics, however, plants of the new cultivar `Ben Vernooij` are more vigorous and produce thicker, strongerleaves and thicker petioles than the parent variety. Additionally, the new variety produces larger foliage and flowers than `First Frost`. Leaves of `Ben Vernooij` have a wider yellow margin than `First Frost`.

COMMERCIAL COMPARISON

`Ben Vernooij` can be compared to the commercial variety Hosta hybrid `Sleeping Beauty`, unpatented. The varieties are similar in most horticultural characteristics, however, plants of the new cultivar `Ben Vernooij` are more vigorous andproduce thicker, stronger leaves than `Sleeping Beauty. Additionally, the new variety produces larger foliage than `Sleeping Beauty` and have foliage with a wider yellow margin than `Sleeping Beauty`.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of `Volcano Island` grown outdoors. This plant is approximately 6 months old, shown in a 1 liter pot.

FIG. 2 illustrates a flowering plant.

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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007, except where general terms of ordinary dictionary significance are used.
