plant named ‘Terms of Endearment’

Abstract

A new and distinct Hosta plant named ‘Terms of Endearment’ of large, arching mounds of broadly ovate, bluish-green leaves having wide chartreuse margins upon emerging and maturing to creamy-yellow margins. The variegation is also attractively displayed with numerous featherings of intermediate colors between the center the leaf margins. The flowers are very pale purple to near white held just above the foliage beginning in late June for about four and a half weeks. ‘Terms of Endearment’ has excellent very large mounded habit and is useful in the landscape, as a specimen or en masse.

Description

Botanical classification: Hosta hybrid (Tratt.).

Variety denomination: ‘Terms of Endearment’.

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

Hosta ‘Terms of Endearment’ was first introduced by the inventor as a non-enabling description through the International Cultivar Registration Authority registration in early 2020. Other non-enabling disclosure include the website introduction by Walters Gardens, Inc. on Feb. 1, 2021 and the “Walters Gardens 2021-2022 Catalog” initially distributed on May 21, 2021. The first enabling disclosure in terms of a sale occurred on Aug. 2, 2021. No plants of Hosta ‘Terms of Endearment’ 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 ‘Terms of Endearment’ hereinafter also referred to as the new plant or by the cultivar name, ‘Terms of Endearment’. Hosta ‘Terms of Endearment’ was hybridized by the inventor on Jun. 14, 2012 at a wholesale perennial nursery in Zeeland, Mich., USA. The female parent was a proprietary, unreleased sport known only as “streaked ‘Elegans’” (not patented) and the male parent was ‘Empress Wu’ U.S. Plant Pat. No. 20,774. The new plant was assigned the breeder code 12-84-1 and passed the initial evaluation in the summer of 2014. It 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 ‘Terms of Endearment’ 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 ‘Frances Williams’ (not patented), ‘Northern Exposure’ (not patented), ‘Earth Angel’ (not patented), ‘Band of Gold’ (not patented) and ‘Wu-La-La’ U.S. Plant Pat. No. 31,309.

‘Frances William’ (a sport of ‘Elegans’) maintains a more yellowish variegated margins throughout the growing season, and the leaves are susceptible to burning appearing necrosis when mature. ‘Northern Exposure’ has more white variegated margin and ‘Terms of Endearment’ has a more yellowish variegated margin. ‘Earth Angel’ has leaves that are less bullate and more cordate in shape, the leaf margins are more creamy-yellow in maturity. ‘Band of Gold’ is more compact in habit, the leaf margins are lighter creamy-colored, and the flowers are higher above the foliage. ‘Wu-La-La’ has a more cordate leaf that is less bullate and less glaucous, the margin is not as broad and of a more chartreuse hue.

Other Hosta cultivars may have individual traits similar to ‘Terms of Endearment’ 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 very large-sized, broadly ovate, with broadly acute apices and cordate base;
  • 2. Arching leaves have a moderately-wavy chartreuse margin upon emerging and mature to a creamy-yellow;
  • 3. Leaf center is bluish-green with numerous featherings of intermediate colors between the margin and center;
  • 4. Flowers are pale purple to near white, densely arranged on scapes with the first flowers beginning to open just above the foliage;
  • 5. Very large mounded habit and useful in the garden as edging or front border, in containers, 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 ‘Terms of Endearment’, 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.
