plant named ‘Trendsetter’

Abstract

A new and distinct Hosta plant named ‘Trendsetter’ of medium-sized, arching, long, ovate, medium-green leaves having wavy, yellow, jagged margins with numerous feathering intermediate colors and a narrowly acute curling apex. The flowers are pale lavender beginning in mid-June. ‘Trendsetter’ is attractive and is useful in the landscape, as a specimen or en masse or as a container plant.

Description

Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Trendsetter’.

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

Hosta ‘Trendsetter’ was first introduced by the inventor as a non-enabling description through The American Hosta Society which is the International Cultivar Registration Authority registration in early 2020. No plants of Hosta ‘Trendsetter’ 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.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to a new and distinct Hosta plant, Hosta ‘Trendsetter’ hereinafter also referred to as the new plant or by the cultivar name, ‘Trendsetter’. Hosta ‘Trendsetter’ was a cross by the inventor between two non-patented, unreleased, proprietary hybrids on Jun. 14, 2012 at a wholesale perennial nursery in Zeeland, Mich., USA. The female parent was identified as a proprietary, unreleased sport known only as “streaked ‘Niagara Falls’” (not patented) and the male parent was ‘Empress Wu’ U.S. Plant Pat. No. 20,774. The new plant was assigned the breeder code 12-115-7 and passed the initial evaluation in the summer of 2014. It has been asexually propagated by division at the same nursery since 2017 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 ‘Trendsetter’ is stable and reproduces true to type in successive generations of asexual reproduction.

There are nearly 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 green leaf blades with variegated margins. The most similar Hosta cultivars known to the applicant are ‘Wu-La-La’ U.S. Plant Pat. No. 31,309, ‘Drop-dead Gorgeous’ copending U.S. Plant Patent Application, ‘Bridal Falls’ U.S. Plant Pat. No. 22,413, ‘All that Jazz’ (not patented), ‘Mardi Gras’ (not patented) and ‘Gone with the Wind’ (not patented).

‘Wu-La-La’ has larger, rounder, flatter leaves and thinner variegated margins that are more creamy-colored. ‘Seducer’ has a flatter leaves with less wavy margins and there is frequently a lighter white line between the margin variegation and center. ‘Drop-dead Gorgeous’ is larger in habit with wider variegation. ‘Bridal Falls’ has a more cascading habit with leaves that are more deeply impressed veins and the variegated margin become more creamy-white. ‘All that Jazz’ has broader leaves that are more heart-shaped and the variegated margins is narrower. ‘Mardi Gras’ has broader, more heart-shaped leaves with wider margins of creamy white becoming white. ‘Gone with the Wind’ has narrower variegated margins and more narrow upright habit.

The female parent has leaves with random streaked variegation in the margin and a center of green and cream with wavy leaf margins and deeply impressed veins. The male parent has a larger habit and leaves of medium green having smoother veins and lack the wavy margins that are not variegated.

Other Hosta cultivars may have ovate leaf blades with yellow variegated margins and blue-green centers, thick leaf substance or other individual traits similar to ‘Trendsetter’ 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. Large cordate leaves of medium green, with slightly twisted acute apices and cordate base;
  • 2. Leaves have a wavy, jagged, yellow margin and a narrowly acute curling apex;
  • 3. Flowers are pale lavender beginning in mid-June for about four and a half weeks;
  • 4. Medium-size mounded habit useful in the garden as edging or border, as a specimen or en masse.

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 ‘Trendsetter’, has not been observed under all possible environments. Those skilled in the art will appreciate that certain characteristics will vary with 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.
