BACKGROUND AND ORIGIN OF THE PLANT
The present invention relates to the new and distinct Hosta plant, Hosta
Clovelly' discovered by
Kent Terpening in North Syracuse, N.Y. as the result
of a self crossing of Hosta Split Decision' (not
patented). The plant has been successfully asexually
propagated by tissue culture methods at a
nursery in Zeeland, Mich. and found to be stable and produce
identical plants that maintain the unique
characteristics of the original plant.
SUMMARY OF THE PLANT
Hosta 'Clovelly' differs from its parent, 'Split Decision, as
well as all other hostas known to the applicant.
The most similar known hosta cultivars: 'Niagara Falls' (not patented), 'Candy Dish' (not patented) and 'Split Decision' (not patented) are all green cultivars
with sinuate margins. 'Niagara Falls' has a cascading
habit and is larger in both habit and leaf size. 'Split Decision' has more drawn out and pointed leaf apex with
a smaller ratio of leaf width to leaf lengtH. 'Candy Dish' has shiny upper and lower leaf surfaces and is
smaller in habit and leaf size and larger ratio of width
to lengtH. 'Clovelly' has a matte upper surface texture,
a slightly shiny lower leaf surface, and the leaves are
more horizontal than 'Niagara Falls'. Hosta 'Clovelly' has a longer drawn-out leaf apex (more
sharply pointed) than 'Candy Dish' and 'Niagara Falls,
but less pointed than 'Split Decision'. Hosta 'Clovelly' has a sinuate margin similar to 'American Icon' U.S. Plant Pat. No. 17,441, but the new plant is
smaller and is solid green.
There are over 3,600 cultivars registered with
The American Hosta Society, which is the
International Cultivar Registration Authority for the
genus Hosta. Hosta Clovelly' differs from these
and all unregistered cultivars known to the inventor in
that it has:
o
1. Rich green foliage with deeply undulated margins
creating a sinuate edge;
o
2. Compact habit, medium-sized clumps;
o
3. Tightly clustered flowers on scapes above foliage
high enough for each medium lavender flower to be
effectively displayed, each flower subtended by a bract
with light lavender center accenting and closely
matching the flower color.
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.

and deeply impressed veins
FIG. 2 shows the plant in midseason.
FIG. 3 shows the foliage flower scape.

pattern.
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 Clovelly,
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 three-year old plant in a
garden in Zeeland, Mich. under light artificial shade
canopy with supplemental water and fertilizer.

(underside): closest to RHS 138A. The 9 to 11 vein pairs
on either side of midrib are the color is the same as
the surrounding leaf tissue on both the top and bottom
of the leaf; midrib on abaxial side is lighter than RHS
138D toward base of leaf becoming RHS 138A toward apex;
midrib on adaxial side is RHS 144A in the one third
closest to the base developing to RHS 137 A in the one
third nearest the apex. PetiolesL 20 to 25 cm (10 in.) long, 8 to
