Abstract: A new and distinct Hosta plant cultivar is disclosed, characterized by a better performance in the sun than other Hosta varieties known to the inventor; large, oval-shaped leaves; very low cold requirements and bright green leaves with wide, creamy yellow-white margins.
Claim: What is claimed is:

1. A new and distinct cultivar of Hosta plant named `HOST SUN 08` as herein illustrated and described.
Description: Latin nameof the genus and species: Hosta hybrida.

Variety denomination: `HOST SUN 08`.


The new cultivar `HOST SUN 08` is a naturally occurring chimeral mutation of the variety `So Sweet` (unpatented in the United States). The new cultivar was discovered and selected by Bernard Chodyla in April 2004 in Crawfordville, Fla.

Asexual reproduction of the new cultivar `HOST SUN 08` by division and tissue culture was performed in Crawfordville, Fla. and Oxnard, Calif., and has shown that the unique features of this new cultivar are stable and reproduced true to type onsuccessive generations.


The cultivar `HOST SUN 08` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `HOST SUN 08`. These characteristics in combination distinguish `HOST SUN 08` as a new and distinct Hosta cultivar: 1. Performs better inthe sun than other Hosta varieties known to the inventor; 2. Very low cold requirements; 3. Bright green leaves with wide, creamy yellow-white margins.

Plants of the new cultivar `HOST SUN 08` are similar to plants of the parent variety, `So Sweet` in most horticultural characteristics, however `HOST SUN 08` is slightly shorter than the parent variety. Also, the leaves of `HOST SUN 08` havebroader white-colored edges and a lighter green color than the leaves of the parent variety. Finally, `HOST SUN 08` performs better in the full sun and has a lower cold requirement.

In comparison to the commercially available variety `Forest Fire` (U.S. Plant Pat. No. 17,644), `HOST SUN 08` is taller and has a wider plant spread. Additionally, the foliage of the new variety `HOST SUN 08` is a much brighter green than thefoliage of `Forest Fire`. Further, the markings on the foliage of the new variety `HOST SUN 08` are different in shape than `Forest Fire.` Finally, `HOST SUN 08` performs better in the sun and has a lower cold requirement.


The accompanying photograph illustrates in full color a typical plant of `HOST SUN 08` grown in an outdoor garden. The colors are as nearly true as is reasonably possible in a color representation of this type.


In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe `HOST SUN 08`plants grown in Oxnard, Ventura County, Calif., during the months of December through February. The growing temperature ranged from C. to C. at night to C. to C. during the day. Measurements and numericalvalues represent averages of typical Hosta plants. Botanical classification: Hosta hybrid cultivar `HOST SUN 08`. Commercial classification: Hosta.


Method: By sterile laboratory tissue culture division and garden division. Time to initiate roots from both division and tissue culture: Two to three weeks. Rooting habit: Normal, fleshy, lightly branching.


Form: Annual potted or garden plant. Growth habit: Mounded plant form with broadly spreading foliage. Branching habit: Very well branched plant with multiple glossy leaves. Crop time: Under normal summer growing conditions about 16 weeks tofinish in a one-liter container. Vigor: Good to high; it takes about 12 month to produce fully grown plants from tissue culture micros. Longevity: `HOST SUN 08` is the last variety known to the inventor to go dormant. In zones 10a and 10b it will staygreen year around, plants will bloom in April if planted in the fall. In other zones where subject to winter dormancy, `HOST SUN 08` will bloom in July and August. Plant height: About 60 cm. Plant diameter: About 52 cm.

Disease resistance: Very resistant to pest and disease. Drought tolerance/cold tolerance: `HOST SUN 08` performs best in the full sun and hot, humid conditions of the Southeast. Plants will express its full white variegation in full sun only. `HOST SUN 08` has very low cold requirements comparing to other Hosta varieties known to the inventor. It will stay vegetative under short days during winter months in South Florida. It has a very good drought tolerance. Fruit/seed production:Commercially, this plant is not used or observed in a stage where seeds would be produced. Therefore, seed production has not been observed.
