I claim:

1. A new and distinct ornamental plant cultivar named Hosta ‘Royal Wedding’ as herein described and illustrated.



Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Royal Wedding’.


There are over 5,000 registered Hosta cultivars with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta and a similar number of unregistered cultivars. Only one species and a small number of these cultivars have fragrant flowers, and a smaller number still have variegated foliage and white flowers. Hosta ‘Royal Wedding’ is a natural, un-induced, whole-plant mutation from ‘Diana Remembered’ (not patented). ‘Diana Remembered’ is a stable variegated form of the streaked and unstable cultivar Hosta ‘Seventh Heaven’ (not patented) which is a selection from a cross between Hosta ‘Kevin Vaughn’ (not patented)×Hosta plantaginea. Other fragrant, light-margined hostas include: ‘Austin Dickinson’ (not patented), ‘Emily Dickinson’ (not patented), ‘Fragrant King’ (not patented), ‘Fragrant Queen’ U.S. Plant Pat. No. 19,508, ‘Iron Gate Glamour’ (not patented), ‘Iron Gate Special’; (not patented), ‘Mistress Mabel’ (not patented), ‘So Sweet’ (not patented), ‘Summer Fragrance’ (not patented) and ‘White Margin’ U.S. Plant Pat. No. 8,015. All of the above Hosta cultivars have fragrant flowers and variegated foliage with green centers and lighter margins.


This invention was developed without any federally sponsored research or development funding.


The present invention relates to a new and distinct hosta plant, Hosta ‘Royal Wedding’ hereinafter also referred to as the new plant or just the cultivar name, ‘Royal Wedding’. Hosta ‘Royal Wedding’ was discovered by Amy J. Bergeron as a non-induced, naturally-occurring, whole-plant mutation in a batch of tissue cultured propagated Hosta ‘Diana Remembered’ (not patented) at a wholesale nursery greenhouse in Zeeland, Mich., USA on Mar. 29, 2010. The new plant has been asexually propagated by division at the same nursery in Zeeland, Mich. USA since 2012 and also by careful shoot tip plant tissue culture with the resultant asexually propagated plants having retained all the same traits as the original plant. ‘Royal Wedding’ is stable and reproduces true to type in successive generations of asexual reproduction.


The nearest comparison variety is Hosta ‘Diana Remembered’, and the new plant, ‘Royal Wedding’, differs by having wider variegated margins, thicker substance to the foliage and slightly darker green leaf centers.

Distinctions between the above listed comparison cultivars and the new plant are further delineated in Table 1 below.

Other Hosta cultivars have short habit and variegation of a similar nature, or other individual traits similar to ‘Royal Wedding’ but the new plant differs from the above cultivars and all other hostas known to the applicant, by the combination of the following traits:

    • 1. Compact rounded plant habit;
    • 2. Variegated foliage with wide creamy-white to near-white margins, green center and minor intermediate feathered colors between;
    • 3. White fragrant flowers just above foliage; and
    • 4. Stiff scapes and leaves with thick substance.


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, temperature, source and direction may cause the appearance of minor variation in color.

The first drawing shows a three-year old Hosta ‘Royal Wedding’ plant in a container in mid-season grown in a shaded greenhouse at a nursery in Zeeland, Mich. with supplement fertilizer and water as needed.

FIG. 2 shows a close-up of the scape and flowers of Hosta ‘Royal Wedding’.


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 ‘Royal Wedding’, 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 potted three-year old plant in a shaded greenhouse in Zeeland, Mich. with supplemental water and fertilizer.

  • Disease tolerance and resistance: The new plant has not shown any resistance to pests and diseases common to hostas. Hosta ‘Royal Wedding’ is capable of tolerating more heat and sunlight than typical hostas and requires less vernalization to emerge and grow well. The plant grows best and shows best coloration with plenty of moisture, adequate drainage and light shade, but is able to tolerate some drought when mature, and tolerates direct sun without leaf burn, especially during the cooler parts of the day and when provided sufficient water. Hardiness at least from USDA zone 3 through 9, and other disease resistance is typical of that of other hostas.
