Hosta 'Eye Declare'


According to the U.S. government, a new Hosta cultivar is an "invention". Therefore, it is eligible to receive a patent, just like Edison's electric light bulb. In the case of hostas and other plants, a patent means that for the next 20 years, nobody may propagate and sell this cultivar without providing compensation to the owner of the patent. This is a different process than registering a Hosta with The American Hosta Society.

The application for a patent must include a tremendous amount of information about the plant. Measurements of every conceivable part of the plant are given in metric terms. The color of all plant tissues are given in terms of representations on the Royal Horticultural Society Colour Chart (RHS).

Shown below is the extensive patent information for this cultivar as it was listed on FreePatentsOnline.com:

SUMMARY, BACKGROUND AND ORIGIN OF THE PLANT

The new and distinct Hosta plant, hereinafter also referred to as 'Eye Declare' and “the plant” is a new and distinct cultivar of hosta. It was found by Clarence (C.H.) Falstad, III in October of 1999 as an un-induced whole plant sport of the Hosta cultivar 'Sea Fire' (not patented) at a tissue culture facility at a nursery in Zeeland, Mich. Hosta Sea Fire' is a hybrid of Mrs. Mildred Seaver formerly of Needham Height, Mass. The plant has been successfully propagated by division and tissue culture methods at the same perennial plant nursery in Zeeland, Mich. and found to produce identical plants that maintain the unique characteristics of the original plant. The plant is stable and reproduces true to type in successive generations of asexual reproduction.

Hosta 'Eye Declare' differs from its parent sport, 'Sea Fire' as well as all other hostas known to the applicant, in that the plant is variegated with a viridescent yellow center emerging in the spring with a very light butter yellow and dark green margin. With warmer summer temperatures the center color gradually develops to a light to medium green. Hosta Sea Fire' also has another sport: 'St. Elmo's Fire' (not patented), which has the same viridescent yellow center with a white margin.

The most similar known hosta cultivar is 'Paradise Power' U.S. Plant Pat. No. 12,117. Both cultivars are yellow with a green margin, but 'Eye Declare' is viridescent and 'Paradise Power' is lutescent. 'Paradise Power' is also much larger and has a longer more pointed leaf than 'Eye Declare'. 'Paradise Power' also does not possess the red stippling that 'Eye Declare' has in the leaf petiole and scape and seed pod. Several other cultivars with yellow leaf centers and green margins also exist, but with fewer similarities to the plant.

BRIEF DESCRIPTION OF THE DRAWINGS

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

GENERAL DESCRIPTION OF THE PLANT

The genus Hosta is mainly native to Japan with a few species originating from China and Korea. There are over 3,300 cultivars registered with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta. Hosta 'Eye Declare' differs from all of these known to the inventor in that it has:

o    1. Light yellow foliage early in the season margined with a dark green border

o    2. Pendulous light lavender flower on scapes well above foliage.

o    3. Red stippling on leaf petioles and flower scape.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hosta Eye Declare’, has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture and maturity levels, but without any change in the genotype. The following observations and size descriptions are of a four-year old plant in a garden in Zeeland, Mich. under 50% shade cloth with supplemental water and fertilizer.

 + Botanical Classification: Hosta × hybrid.

 
+ Parentage:
Naturally occurring sport of Hosta 'Sea Fire' (not patented).

 
+ Propagation:
     

§  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, slightly branching.

 
+ Plant description:
     

§  Plant shape and habit. Hardy herbaceous perennial with basal rosette leaves, symmetrical and arching over.

§  Crop time. Under normal summer growing conditions about 16 weeks to finish in a one-liter container. Plant vigor is good to high.

§  Plant size. Foliage height at flowering is 30 to 35 cm (13.7 in.) tall from soil line to the top of the leaves and 45 to 50 cm (19.6 in.) wide at soil line.

 
+ Foliage description:
     

§  Shape and size. Elliptic to cordate leaf blades have an acute apex and rounded base. The leaf blades are 18 cm (7 in.) to 20 cm (7.9 in.) long and 12 to 7.0 cm (2.8 in.) wide. The leaf blade margin is entire and the variegation pattern on the darker edge varies in different regions of the leaf from 2 to 10 mm wide. The leaves have between 10 and 11 pairs of major parallel veins. Top surface is dull without significant glaucous bloom, and bottom surface is shiny. There is a slight dimpling running between the veins.

§  Blade color. Young emerging Leaves: Top surface center and margin respectively: RHS 3B; RHS 141B. Underside center and margin respectively: RHS 3B; RHS 141B or RHS 141C, Some intermediate colors on top and bottom with the major portion between RHS N144A and RHS N144C. Top surface of mature Leaves: Top surface center and margin respectively: Between RHS 145C and RHS 157D; RHS 139A. Underside center and margin respectively: between RHS 144A and RHS N144A; between RHS 139A and RHS 141 A. The intermediate color bands on the top and bottom surfaces of mature leaves develop a deeper green less distinguishable from the margin color. In more sun the center color of the mature leaves bleaches to an RHS 157C on the leaf back and between RHS 145 C and RHS 157 D on the top. Veins color is the same as the surrounding leaf tissue on both the top and bottom of the leaf.

§  Petioles. 16 to 18 cm (7 in.) long and 1.0 to 1.4 cm (0.6 in.) wide. The leaf margin continues down the petiole 1 to 2 mm wide and RHS 141 C on young foliage on both top and back while center is nearest RHS 145 A on both surfaces. On older foliage the petiole the margin of both surfaces is RHS 143 A, and the center gradually lightens going toward middle to RHS 144A. The petiole is also heavily stippled with RHS 183 B on the inside and even numerous stipples of RHS 183 C on the back outside surface.

+ Disease resistance:
Resistance beyond that of other hostas has not been observed. The plant grows best with plenty of moisture and adequate drainage, but is able to tolerate some drought when mature. Hardiness at least from USDA zone 3 through 9, and other disease resistance is typical of that of other hostas.
 
RHS Colour Chart - The Royal Horticultural Society in the United Kingdom has produced a color tool that resembles a paint chart with over 920 samples. It is used by horticulturists around the world to identify colors of flowers, fruits and plant parts in order to bring a level of consistency. Each color has its own unique name along with a number and letter code.
