Abstract: A distinct cultivar of Hosta plant named `El Nino`, characterized by its relatively compact plant habit; bluish green and white variegated leaves; freely flowering habit; and violet blue-colored flowers that are positioned above the foliage on erect scapes.
Claim: It is claimed:

1. A new and distinct cultivar of Hosta plant named `El Nino`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Hosta tardiflora cultivar El Nino.


The present Invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta tardiflora, and hereinafter referred to by the cultivar name El Nino.

The new Hosta originated from a cross-pollination in 1996 of the Hosta tardiflora cultivar Halcyon, not patented, as the female, or seed, parent with an unidentified selection of Hosta tardiflora, not patented, as the male, or pollen, parent. The cultivar El Nino was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled environment in Noordwijk, The Netherlands.

Asexual reproduction of the new cultivar since March, 1999, by divisions harvested in Noordwijk, The Netherlands, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations.


Plants of the cultivar El Nino have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature 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 `El Nino`. These characteristics in combination distinguish `El Nino` as a new and distinct cultivar: 1. Relatively compact plant habit. 2. Bluish green and white variegated leaves. 3. Freely flowering habit. 4. Violet blue-colored flowers that are positioned above the foliage on erect scapes.

Plants of the new Hosta can be compared to plants of the female parent, the cultivar Halcyon. Plants of the new Hosta differ primarily from plants of the cultivar Halcyon in leaf coloration as plants of the cultivar Halcyon have solid bluishgreen-colored leaves.


The accompanying colored photographs illustrate the overall appearance of the new Hosta, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly fromthe color values cited in the detailed botanical description which accurately describe the actual colors of the new Hosta.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of `El Nino`.

The photograph at the top of the second sheet is a close-up view of typical leaves of `El Nino`.

The photograph at the bottom of the second sheet is a close-up view of typical flowers of `El Nino`.


In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs andfollowing description were about five years old and grown in an outdoor nursery and under conditions which closely approximate commercial production conditions during the summer in Noordwijk, The Netherlands.
