Abstract
A new and distinct Hosta plant named ‘Royal Crest’ with medium rounded-mound habit of heavy-substance, cordate foliage having slightly wavy margins, acute apex and cordate base with deep green color. The plant has large, white, strongly-fragrant, broadly-faced flowers densely arranged on stiff upright scapes above the foliage beginning in early August.
Description
Latin name and variety denomination of the plant:
Botanical classification: Hosta hybrid (Tratt.).
Variety denomination: ‘Royal Crest’.
The first public disclosure of the claimed plant, in the form of a website to the public and email release to customers, was made by Walters Gardens, Inc. on Feb. 1, 2018 followed by the Walters Gardens, Inc. Summer 2018-Spring 2019 catalog on Jun. 5, 2018. The first public sales of Hosta ‘Royal Crest’ was by Walters Gardens, Inc. on Jun. 10, 2019. Walters Gardens, Inc. obtained the new plant and information about the new plant directly from the inventor. No plants of Hosta ‘Royal Crest’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.
The present invention relates to a new and distinct hosta plant, Hosta ‘Royal Crest’ hereinafter also referred to as the new plant or just the cultivar name, ‘Royal Crest’. Hosta ‘Royal Crest’ was a cross by the inventor at a wholesale nursery in Zeeland, Mich., USA on Aug. 31, 2009. The female parent was a proprietary, induced, tetraploid mutation of ‘Royal Standard’ (not patented). The male parent was ‘Braveheart’ (not patented). The new plant passed the initial evaluation in 2011 and was assigned the breeder code H9-109-01 through the remaining trial period. The new plant has been asexually propagated by division at the same nursery in Zeeland, Mich., USA since 2014 and also by careful plant shoot-tip tissue culture with the resultant asexually propagated plants having retained all the same traits as the original plant.
There are over 6,000 registered hosta cultivars with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta along with a similar number of unregistered cultivars. The nearest known comparison cultivars are Hosta ‘Braveheart’, ‘Old Faithful’ (not patented), ‘Fried Green Tomatoes’ (not patented) and ‘Royal Standard’ (not patented).
All of the above plants have fragrant flowers. ‘Braveheart’ has a smaller foliage, flatter habit and more lavender flowers. ‘Old Faithful’ has more lavender flower buds and very pale lavender flowers that are not as white, the scapes are more arching, the petioles tend to have a reddish coloring near the base, and it forms a larger clump. ‘Fried Green Tomatoes’ has solid green foliage, but the leaves are more arching and the leaf substance is not as thick, the flower stems are more outwardly and the tepals are a very pale lavender. ‘Fried Green Tomatoes’ flower about two weeks earlier than the new plant. ‘Royal Standard’ has solid green foliage, but the leaves are more arching and the leaf substance is not as thick.
Other Hosta cultivars have variegated foliage, but ‘Royal Crest’ is distinct from the above listed hostas and all other cultivars known to the inventor by the following combined traits:
-
- 1. Medium rounded-mound plant habit with dense foliage with deep green leaves;
- 2. Heavy-substance, stiff leaves of cordate shape and acute apex and cordate base;
- 3. Leaves moderately shiny surface above and strongly shiny below with slightly sinuate margins;
- 4. Large flowers on stiff upwardly projecting scapes above foliage are white, broad-faced, strongly-fragrant beginning in early August.
The photographs of the new plant demonstrate the overall appearance of the new 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 following descriptions and color references are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hosta ‘Royal Crest’, 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 five-year old plant in a partially shaded trial garden and container grown plant in a greenhouse in Zeeland, Mich. with supplemental water and fertilizer.
