BACKGROUND OF THE INVENTION
The present invention relates to the new and distinct Hosta plant, Hosta ‘Bridal Falls' discovered
Hendrik Jan van den Top at a nursery in Barneveld,
The Netherlands in the summer of 2009 as an uninduced
whole plant mutation in a tissue cultured crop of Hosta ‘Niagara Falls' (not patented). The new plant
has been successfully asexually propagated by division
nursery in Zeeland, Mich. and by sterile plant
tissue culture, and in both asexual propagation systems
found to be stable and produce identical plants that
maintain the unique characteristics of the original
BRIEF BRIEF SUMMARY OF THE INVENTION
Hosta 'Bridal Falls' differs from its sport parent, 'Niagara Falls’, as well as all other hostas known to the
applicant. Other similar varieties include: Hosta 'Crispula' (not patented), 'Gone with the Wind' (not
patented), 'Lonesome Pine' (not patented), 'Silk Kimono' (not patented), 'Zippity Do Dah' (not patented. 'Crispula' has a longer and more pointed leaf shape, the
margin emerges whiter and the flowers are paler
lavender. 'Gone with the Wind' leaves are less arching
in maturity, less sinuate or undulate in the margin and
longer and more pointed than the new variety. 'Lonesome Pines' is also less arching foliage, the leaf apex is
less acute and leaf margin less sinuate. 'Silk Kimono' has fewer leaf vein pairs that are also less pronounced
or less impressed and less sinuate margins. 'Zippity Do Dah' has more elongated and narrower leaves with fewer
vein pairs and the leaf blade is more coarsely sinuate
rather than the intense undulations confined to the leaf
margins. All of the above cultivars have green leaf
centers with white to creamy-yellow margins having
margins or coarse waves throughout the leaf blades, but 'Bridal Falls' has a more intense sinuate or rippled (piecrusting)
margin with the reminder of the leaf flat except for the
intensely impressed veins. 'Bridal Falls' differs from
its mutation parent, 'Niagara Falls’, by having a broad
creamy yellow margin upon leaf emergence that develops
to a creamy-white to white.
There are over 4,950 cultivars registered with The American Hosta Society, which is the
International Cultivar Registration Authority for the
genus Hosta and a similar number of unregistered
cultivars. Hosta ‘Bridal Falls' differs from all
these registered and unregistered cultivars known to the
inventor in the following combined traits:
1. Plant of large size with foliage that arches over in
2. Cordate leaves with green centers and sinuate or
undulate margins of creamy yellow margins upon leaf
emergence that develops to a creamy white to white.
3. Foliage has deeply impressed veins above and sharply
ridged veins below.
4. Numerous light-lavender slightly pendulous flowers on
erect scapes well above foliage with large bracts below
each flower having similar color to flowers.
BRIEF DESCRIPTION OF THE DRAWINGS
The photographs of the two-year old plant demonstrate
the overall appearance of the plant, including the
unique traits, grown in a partially shaded greenhouse in
Zeeland, Mich. The colors are as accurate as reasonably
possible with color reproductions. Ambient light
spectrum, source, direction and temperature may cause
the appearance of minor variation in color.

the early part of the growing season.

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 ‘Bridal Falls’, has not been observed under all possible
environments. The phenotype may vary slightly with
different environmental conditions, such as temperature,
light, fertility, growth rate, moisture and specimen
maturity, but without any change in the genotype. The
following observations and size descriptions are of a
two-year old plant in a greenhouse in Zeeland, Mich.
