I claim:

1. A new and distinct ornamental Hosta plant named ‘Bridal Falls’ as herein described and illustrated, with cordate leaves having dark green centers and wide creamy yellow margins that develop into a creamy white to white, light lavender flowers on large-sized plant, suitable as a potted plant, for landscaping the garden, and for cut flower or leaf arrangements.


Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Bridal Falls’.


The present invention relates to the new and distinct Hosta plant, Hosta ‘Bridal Falls’ discovered by 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 at a 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 plant.


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 maturity.
    • 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.


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.

FIG. 2 shows a close-up of the flower in early August.


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. with white plastic glazing and light fertilizer.
