plant named ‘Dancing in the Moonlight’

Abstract

A new and distinct Hosta plant named ‘Dancing in the Moonlight’ producing medium-sized upright mounds of basal, lanceolate leaves with long, narrowly acute apices, cordate bases and intensely wavy margins and strongly folded along the midrib. The leaves are variegated having medium green centers and creamy-white margins with intermediate color separation between the margin and center of variably large segments of several shades of chartreuse. The medium-sized leaves have a matte and lightly glaucous upper surface and heavily glaucous underside. The campanulate flowers are very pale lavender beginning in mid-July. Each flower is attractively subtended by a floral bract with purplish margin making the scape showy for long periods. ‘Dancing in the Moonlight’ is useful in the landscape, as a container plant, a specimen or en masse.

Description

Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Dancing in the Moonlight’.

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

Hosta ‘Dancing in the Moonlight’ was first introduced by the inventor as a non-enabling description in registration of the name in early 2021 with the International Cultivar Registration Authority for the genus Hosta. No plants of Hosta ‘Dancing in the Moonlight’ have been sold in this country or anywhere in the world, nor has any enabling disclosure of the new plant been made.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to a new and distinct Hosta plant, Hosta ‘Dancing in the Moonlight’ hereinafter also referred to as the new plant or by the cultivar name, ‘Dancing in the Moonlight’. Hosta ‘Dancing in the Moonlight’ was hybridized by the inventor on Jul. 14, 2015, at a wholesale perennial nursery in Zeeland, Mich., USA. The female parent was the proprietary unreleased hybrid known only by the hybrid number H10-132 (not patented) and the male parent was the proprietary unreleased hybrid known only by the hybrid number H10-366 (not patented). The seeds from this cross were planted in late fall of 2015 and a single seedling selection from this cross eventually was selected as the new plant. The new plant was assigned the breeder code 12-132-4 and passed the initial evaluation in the summer of 2018. ‘Dancing in the Moonlight’ has been asexually propagated by division at the same nursery since 2018 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. Hosta ‘Dancing in the Moonlight’ has been stable and reproduced true to type plants in successive generations of asexual reproduction.

There are over 7,000 registered and established Hosta cultivars with The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta. Several of these have blue-green leaf blades. The most similar Hosta cultivars known to the applicant are: ‘Minnesota Wild’ (not patented), ‘High Diver’ (not patented), ‘Barracuda’ (not patented), and ‘Summer Wind’ (not patented).

The female parent is much smaller with green foliage that was irregularly streaked with creamy white. The male parent has solid bluish-green, rippled, and arching foliage.

‘Minnesota Wild’ has a more rounded less upright habit, the leaves are broader with less acute apices, more consistent and wider margins, less folded, and less sinuate. ‘High Diver’ has leaves that are less sinuate and less folded. ‘Barracuda’ is smaller and more arching in habit with a more lustrous, less sinuate and less folded leaves. ‘Summer Wind’ has more arching habit, the foliage that is less sinuate, and less folded-green.

Other Hosta cultivars may have individual traits similar to ‘Dancing in the Moonlight’ but the new plant differs from the above listed cultivars and all other Hostas known to the applicant, by the combination of the following traits.

• • 1. Leaves are medium-sized, lanceolate, with long, narrowly, acute apices and cordate bases;
  • 2. Leaves are furrowed with an intensely wavy margin with twisted leaf apices;
  • 3. Leaf margins are creamy white, the mature center color is medium green with intermediate color separation between the margin and center;
  • 4. Campanulate flowers are very pale lavender on upright, light-green, moderately glaucous scapes beginning in mid-July;
  • 5. Flowers are moderately loosely arranged on scapes with the first flowers beginning to open well above the foliage;
  • 6. Floral bracts with a purplish margin subtend each flower;
  • 7. The habit is a medium-sized upright mound.

DETAILED BOTANICAL DESCRIPTION

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 ‘Dancing in the Moonlight’, has not been observed under all possible environments. Those skilled in the art will appreciate that certain characteristics will vary in plants that are more mature or plants that are less mature. 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.
