Abstract

A new and distinct Hosta plant named `Wild Imagination` with medium-sized, rounded-mound habit of glaucous, bluish-green, long thin foliage. Leaves have are twisted distally and very wavy margins. The plant produces light purple flared campanulate flowers on numerous upright scapes well above the foliage beginning in late July and continuing for about five weeks.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)

The non-enabling disclosure of the claimed plant, in the form of cultivar registration with The American Hosta Society which is the International Cultivar Registration Authority for the genus Hosta was by the inventor in December 2020 with public printing in early 2021. No plants of Hosta `Wild Imagination` 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.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to a new and distinct Hosta plant, Hosta `Wild Imagination` hereinafter also referred to as the new plant or just the cultivar name, `Wild Imagination`. Hosta `Wild Imagination` is the result of an intentional cross by the inventor on Jul. 31, 2012 at a wholesale perennial nursery greenhouse in Zeeland, Mich., USA. The female parent is Hosta `Electrocution` (not patented) and the male parent is an unreleased proprietary hybrid known only by the breeder code H10-366 (not patented). The new plant passed initial evaluation in the summer of 2015, was give the breeder code 12-179-1 and was approved for final selection in the summer of 2018. The new plant has been asexually propagated by division at the same nursery in Zeeland, Mich., USA since 2016 and also by careful plant tissue culture with the resultant asexually propagated plants having retained all the same traits as the original plant. Hosta `Wild Imagination` is stable and reproduces true to type in successive generations of asexual reproduction in both methods.

BRIEF SUMMARY OF THE PLANT

There are nearly 7,000 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 comparison varieties are: `Blue Cascade` (not patented), `Curly Fries` (not patented), `Silly String` U.S. Plant Pat. No. 32,127, `Joy Ride` (not patented), `Fulda` (not patented), and `Neptune` U.S. Plant Pat. No. 19,674.

`Blue Cascade` has glaucous intensely wavy foliage, but the habit and leaves are smaller. `Curly Fries` has a smaller habit, with more arching, narrower, chartreuse foliage that is less glaucous with less intense wavy margins. `Silly String` has a smaller habit with narrower foliage and the flowers are darker purple. `Joy Ride` has a smaller habit with broader and shorter leaf blades that have a coarser marginal wave. `Fulda` has a smaller habit with more glaucous foliage that is flatter and more ovate, and the flowers are pale lavender on shorter scapes. `Neptune` has a larger habit and larger and broader leaves that are more arching and the flowers, the scapes are more arching and flowers pale lavender.

`Electrocution` has narrower leaf blades that are less glaucous, more lustrous, more upright with a creamy white margin. The male parent had glaucous-blue, elongated wedge-shaped leaves and larger habit with a leaf margin that was not nearly as sinuate.

Other similar Hostas include: `Elvis Lives` (not patented), `Pineapple Poll` (not patented), and `Blue Sliver` (not patented). `Elvis Lives` (not patented) has a similar habit with shorter leaves, less sinuate margin and broader and less narrowly acute apices with a scape that is more erect with more numerous flowers. `Pineapple Poll` has foliage with thinner-substance, narrower and leaf blades without glaucous surfaces with less intense sinuate margins. `Blue Sliver` is a smaller plant with less undulation of the foliage and shorter and less narrowly acute apices.

Hosta `Wild Imagination` is distinct from the Hostas listed above and all other cultivars known to the hybridizer by the following combined traits: 1. Medium-sized, rounded-mound plant habit with outwardly, glaucous, blue-green foliage; 2. Foliage has a long, narrowly-lanceolate apex that is moderately twisted with very wavy margins; 3. Light purple, flared, campanulate flowers, well above the foliage, on numerous scapes beginning in late July for about five weeks.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of an eight-year-old plant, including the unique traits of `Wild Imagination`. 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.
