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.
+ Flower description:

day prior to opening lighter than RHS N80 D;
approximately 4.0 cm (1.6 in.) long, up to 1.0 cm (0.4 in.) wide, clavate
with acute apex and longer thin base.
§
Flowers. 38
to 60 per scape; funnelform; 2.5 to 2.8 cm (3.1 in.) wide and 4.0
to 4.5 cm (1.8 in.) long, (distal flowers being smaller), persists
for a normal period, usually one day on or cut from

lighter than RHS N80 D on the outside of both sets with
up to six slightly darker veins of about RHS N 80.
Inside is slightly lighter than RHS N 78 D with up to
six veins of RHS 78 D. Both sets of tepals have white
margins at the basal one third on the inside.

at distal end; Stigma 1 mm to 2 mm in diameter, white.
§

long; Anthers 4 mm long, 1.0 mm wide, RHS 83 A.
§
Pollen. Elliptical,
less than 0.1 mm long, nearest RHS 15 A.
§

center between RHS 143 A and RHS 143 B, with the outside
surface margin RHS 137 B; inside surface center RHS N
144 A and the margin closest to RHS 137 A. Bracts
subtending flowers protrude at about 70 degrees; initial
bracts about 3.0 to 4.0 cm (1.6 in.) long and 1.8 cm (3.1 in.) wide; outside
surface middle portion RHS 194 A with stippling of RHS
59 C, outside surface margin RHS 178 A. Inside surfaces
identical in color to outside.
§
Peduncle. One
per mature division; erect 70 to 90 cm tall and to 8 mm
in diameter, light green color RHS 145 B with reddish
stippling and a light glaucous surface.
§
Pedicel. Approximately
0.8 cm (.31 in.) long, 2 mm wide, RHS 145 B with reddish
stippling, curled downward.
§
Fruit. A
tri-valved capsule, approximately 2.5 cm (1.0 in.) long and 12 mm (0.5 in.)
wide, RHS 183Bwith green undertones. More purple in
higher light, and more green in lower light. Seeds are
black, approximately 1.0 cm (0.4 in.) long and 2 mm wide.
+ 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.
