1. A new and distinct cultivar of Hosta plant named ‘Little Treasure’, substantially as herein shown and described.

Latin name of genus an species of plant claimed: Hosta hybrid (Tratt.).

Variety denomination: ‘Little Treasure’.

The present invention relates to a new and distinct cultivar of Hosta plant botanically known as Hosta hybrid and hereinafter referred to by the cultivar name ‘Little Treasure’.

The new Hosta cultivar is a naturally-occurring sport of ‘Little Jay’, U.S. Plant Pat. No. 11/704,810, characterized by lance-shaped, dwarf-sized, leaves with blue green margins, light yellow to creamy leaf centers, vertical flower scapes with light purple flowers, suitable for landscape, potted culture, or cut flower arrangements. The new cultivar was discovered as a whole plant and selected during August 2005 in a controlled environment at Barneveld, The Netherlands.

Asexual reproduction of the new Hosta by division and tissue culture in a controlled environment in Barneveld, The Netherlands since 2005, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations.

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Little Treasure’ as a new and distinct cultivar of Hosta plant:

Of the many commercially available Hosta cultivars, the most similar in comparison to the new cultivar is the parent cultivar ‘Little Jay’, U.S. Plant Pat. No. 19,539. However, in side by side comparisons, plants of the new cultivar differ from its parent, in leaf color and width of the leaf margin.

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Little Treasure’. The plants were grown outdoors in 3-liter containers for approximately two years in Barneveld, The Netherlands.

The photograph on the first sheet is a side perspective view of typical plants of ‘Little Treasure’ grown in an outdoor nursery.

The photograph at the top of the second sheet is a close-up view of a typical leaf of ‘Little Treasure’.

The photograph at the bottom of the second sheet is a close-up view of a typical inflorescence of ‘Little Treasure’.

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2008 under natural light conditions in Barneveld, The Netherlands when day temperatures ranged from 12° C. to 31° C. (53° ° F. to 88° F.) and night temperatures ranged from 4° C. to 16° C. (39° F. to 61° F.).

Plants used in the following description were grown in Barneveld, The Netherlands, in an outdoor nursery in 3-liter containers and under conditions which closely approximate commercial production conditions. The plants were grown for approximately two years when the description was taken. Measurements and numerical values represent averages of typical plants.
