FEDERALLY SPONSORED RESEARCH

This invention was developed without any federally sponsored research or development funding.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to a new and distinct hosta plant, Hosta ‘Etched Glass’ hereinafter also referred to as the new plant or just the cultivar name, ‘Etched Glass’. Hosta ‘Etched Glass’ was discovered by the inventor at a wholesale nursery in Zeeland, Mich., USA on Jul. 8, 2013 as a whole plant sport in a tissue culture propagated batch of plants of ‘Stained Glass’ (not patented). The new plant has been asexually propagated by division at the same nursery in Zeeland, Mich., USA since 2016 and also by careful plant shoot-tip tissue culture with the resultant asexually propagated plants having retained all the same traits as the original plant.

No plants of Hosta ‘Etched Glass’ have been sold, under this or any other name, in this country or anywhere in the world, prior to the filing of this application, nor has any disclosure of the new plant been made prior to the filing of this application with the exception of that which may have been sold or disclosed within one year of the filing date of this application and was either derived directly or indirectly from the inventor.

BRIEF SUMMARY OF THE PLANT

There are over 5,800 registered hosta cultivars with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta along with a similar number of unregistered cultivars. The nearest known comparison cultivars are Hosta ‘Stained Glass’ (not patented), ‘Cathedral Windows’ U.S. Plant Pat. No. 17,295, ‘Guacamole’ (not patented), ‘Emerald Charger’ (not patented) and ‘Holy Mole’ (not patented).

‘Etched Glass’, ‘Cathedral Windows’ and ‘Emerald Charger’ are all sports of ‘Stained Glass’. ‘Stained Glass’ and ‘Holy Mole’ are sports from ‘Guacamole’. All of the above plants have a green margin and lighter variegated center and lightly fragrant flowers. ‘Guacamole’ has a narrow margin with a chartreuse center. ‘Cathedral Windows’ and ‘Holy Mole’ both have a broader margins with chartreuse centers. ‘Stained Glass’ has a narrow margin with a center that is lighter or more yellowish than ‘Guacamole’. ‘Etched Glass’ has margins that are wider than all the above except ‘Emerald Charger’. ‘Etched Glass’ and ‘Emerald Charger’ both have center variegation with a more yellowish and less chartreuse color than ‘Guacamole’. ‘Etched Glass’ and ‘Emerald Charger’ both have leaves with greater substance that are stiffer than the other above comparison plants.

Other Hosta cultivars have variegated foliage, but ‘Etched Glass’ is distinct from the above listed hostas and all other cultivars known to the discoverer by the following combined traits:

    • 1. Compact rounded-mound plant habit with dense foliage with medium green margins and lighter yellowish leaf centers;
    • 2. Heavy-substance, stiff leaves of cordate shape and acute apex and cordate base;
    • 3. Leaves slightly shiny surface above and below and lightly dimpled between the veins;
    • 4. Flowers on slightly outwardly projecting scapes just above foliage with near white, broad-faced, fragrant flowers.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the new plant, including the unique traits. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
