SUMMARY, BACKGROUND AND ORIGIN OF THE PLANT
The new and distinct Hosta cultivar 'Independence’, hereinafter also referred to as 'Independence' and “the plant” is a new and distinct
plant. It was found by
Jeff A. Westendorp in 1999 as an
un-induced whole plant sport of the Hosta
cultivar 'Revolution' (not patented) growing in a
greenhouse in a
nursery in Zeeland, Mich., USA. The
plant has been successfully propagated by tissue culture
and division methods at the same nursery 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 'Independence' differs from its parent sport, 'Revolution’, in that the color pattern is completely
reversed in the leaf. 'Revolution' has the white center
with green speckling within and a dark green margin. 'Independence' has a white margin with the green
speckling within and a green center. The most similar
known hosta cultivar is 'Lakeside Zinger' which
has the same color pattern as 'Independence' but the
margin is much wider on 'Independence'. The new plant is
also about twice the size in total habit and leaf
dimensions, and the thickness of the leaf of 'Independence' from top to bottom surface is much

appearance of the plant, including the unique traits.
The colors are as accurate as reasonably possible with
color reproduction. Ambient light spectrum, source and

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 'Independence' differs from all of these in that it has:
1. Very thick substance in the leaves
2. Deep green coloring
3. Upright habit in youth
4. Wide creamy white leaf margins
5. The margins contain numerous green flecks of various
6. 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 'Independence’, 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 two-year old
plant in a two-gallon container grown in Zeeland, Mich.,
USA under 50% shade on cloudless days, day temperatures
of 18 cm (7 in.) to 28 degrees C., and night temperatures of 15 to
20 degrees C.
+ Botanical Classification: Hosta hybrid cultivar 'Independence'.
+ Parentage: Naturally occurring sport of Hosta 'Revolution' (not patented).
tissue culture and division.
Time to initiate roots from both division and tissue
to four weeks.
Rooting habit: Normal,
fleshy, slightly branching.
+ Plant description:
Plant shape and habit: Hardy
herbaceous perennial with basal rosette leaves,
symmetrical, upright and erect through flowering period;
more horizontal in older plants.
Crop time: Under
normal growing conditions about 22 weeks to finish in a
one-liter container. Plant vigor is good to high.
Plant size: Foliage
height at flowering is 25 to 33 cm (13 in.) tall from soil line
to the top of the leaves and 23 to 28 cm (11 in.) wide.
+ Foliage description:
Shape and size: Ovate
to broadly ovate leaf blades have an acute apex and
cordate base. The leaf blades are 18 cm (7 in.) to 22 cm (8.7 in.) long and
10 to 12 cm (4.7 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.
Texture, both surfaces: Glabrous.
Blade color: Center
portion adaxial surface of young emerging leaves is a
deep green closest to RHS 141 A. Later in the growing
season, the center adaxial surface is between RHS 139 A
and RHS 136 A. The adaxial margin surface is RHS 11 B to
RHS 11 C on young leaves, and whiter than RHS 155 D on
leaves later in the season. The abaxial center color is
RHS 137 A. The abaxial margin color is nearly identical
to the adaxial surface color throughout the seasons.
There are also three or more intermediate color patterns
between the center and the margin. The most prominent
intermediate color bands on the adaxial surface are
yellow-green RHS N138 C and RHS 143 B. Other more
yellow, lighter, or more grayed bands are also sometimes
present in thinner and shorter stripes. The main
intermediate band visible on the abaxial side is RHS 144
C on young leaves with little change over the season.
The green flecks visible on the adaxial side in the
margin are variable and range from RHS 136 A to RHS 138
A and the same color on the abaxial side.
Veins: Parallel, slightly impressed, color on top and bottom of leaf
identical to surrounding variegation.
to 20 cm (7.9 in.) long and 15 mm wide. The 1 to 2 mm wide margin
starts RHS 11 B and lightens to RHS 11 D, but varies
like the leaves depending on how much light the petiole
receives. The center of the petiole is green RHS 136 A
on both surfaces.

pigment RHS 59 B proportional to the amount of sunlight.
Seeds are single winged dark brown drupe about RHS 200 A
to RHS N200 A, 12 to 15 mm long and 3 to 4 mm wide.
+ Disease resistance: The plant is more tolerant of direct
sun, and resists scorching of the light margin more than
most other varieties. The plant is more resistant to
slugs and most pests common to hostas than
Hosta plantaginea in the
parentage, but resistance beyond those hostas of
the Fortunei Group (those of similar genetic
relationship) has not been observed. It grows best with
plenty of moisture and adequate drainage, but is able to
tolerate some drought. Hardiness and other disease
resistance are typical of other hostas, at least
from USDA zone 3 through 9.
