SUMMARY, BACKGROUND AND ORIGIN OF THE PLANT
The new and distinct Hosta plant, hereinafter
also referred to as 'Beckoning' and “the plant” is a new
and distinct cultivar of hosta. It was found by
Timothy Saville in 1998 as an un-induced whole plant sport of
the Hosta cultivar 'Blue Angel' (not patented) in
a now defunct nursery in Cheshire, England. The plant
has been successfully propagated by division and tissue
culture methods at a 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 'Beckoning' differs from its parent sport, 'Blue Angel’,
all other known sports of 'Blue Angel' as well as all
other hostas known to the applicant, in that the plant
is variegated with a lutescent gold center emerging in
the spring as nearly solid colored and gradually
developing the yellow center with warmer temperatures.
Hosta ‘Blue Angel' also has some other sports
including: 'Earth Angel' (not patented), 'Guardian
Angel' (not patented), and 'Fallen Angel' (not
patented). 'Beckoning' has a blue-green margin with a
gold center of each leaf. Hosta ‘Guardian
Angel' has a blue green margin but the center is a misted
whitish-green that tends to become all green in the heat
of the summer. 'Fallen Angel' has the same whitish-green
misting as 'Guardian
Angel' through the entire leaf and
does not have the solid blue-green margin. 'Earth Angel' has a creamy-yellow margin that is lighter than the
center of 'Beckoning’, and has the same blue-green in
the center that 'Beckoning' has on the margin. The most
similar known Hosta cultivars in color are 'June' (not
patented) and 'Paul's Glory' (not patented). 'June' grown in the shade has a similar color pattern as 'Beckoning' grown in the sun, but the new plant is
between two and three times the size of 'June' in habit,
clump height and width as well as leaf size. Hosta
‘Paul's Glory' is slightly smaller in size of leaf
and clump dimensions, and similar in colors, but the
margin is less distinct, or more defused between the
margin and center of the leaf on 'Paul's Glory' and more
distinctly featured or jetting on 'Beckoning'.
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.
FIG. 1 shows the overall plant at the beginning of
flowering.
FIG. 2 shows the leaf later in the season.
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 'Beckoning' differs from all of these in that it has:
o
1. Rugose pointed heart-shaped leaves with blue-green
margins and gold centers
o
2. Large plant size in clump habit and leaf dimensions
o
3. Tall scapes with many light lavender flowers.
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 ‘Beckoning’,
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 Stockport, Cheshire, United Kingdom.
+ Botanical Classification: Hosta ×
hybrid.
+ Parentage: naturally occurring sport of Hosta 'Blue Angel' (not patented).
+ Propagation:
§
Method. By
tissue culture and 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 growing conditions about 18 weeks to finish in a
one-liter container. Plant vigor is good to high.
§
Plant size. Foliage
height at flowering is 45 to 55 cm (21.7 in.) tall from soil line
to the top of the leaves and 50 to 60 cm (24 in.) wide.
+ Foliage description:
§
Shape and size. Cordate
leaf blades have an acute apex and auriculate base. The
leaf blades are 30 to 35 cm (13.7 in.) long and 25 to 30 cm (11.8 in.) wide.
The leaf blade margin is entire and the variegation
pattern on the edge varies in different regions of the
leaf from 10 to 25 mm wide. The leaves have between 16
and 18 pairs of major parallel veins.
§
Blade color. Young
emerging leaves. Top surface margin and center: RHS
137C; Underside margin and center: RHS 191 B.
§
Top surface of mature leaves while still containing
glaucous wax. Top
surface margin: RHS 119A and RHS 116 D. Top surface
center: more yellow than RHS 144B. Underside margin:
more blue than RHS 189A, and more gray than RHS N138A.

+ 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. |
