plant named ‘Seducer’

Abstract

A new and distinct Hosta plant named ‘Seducer’ characterized by cordate leaves having variegated leaf margins of yellowish green, leaf centers of bluish dark green center and developing an irregular thin creamy white intermediate bolt between the margin and center, with near white flowers and light lavender buds on strong erect scapes.

Description

Botanical classification: Hosta hybrid (Tratt.)

Variety denomination: ‘Seducer’.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to the new and distinct hosta plant, Hosta ‘Seducer’ hybridized by Stuart R. Asch in the summer of 1997 at a garden in Clawson, Mich. and was separated as a seedling of potential in the summer of 2001. The new plant is the result of an open-pollination between Hosta ‘Dorothy Benedict’ (not patented) as the female or pod parent and an unknown plant as the male or pollen parent. Hosta ‘Seducer’ has been asexually propagated by division at the garden in Clawson, Mich. and has also been propagated by tissue culture at a nursery in Zeeland, Mich. since the fall of 2006 with all resultant asexually propagated plants having retained all the same traits as the original plant. The plant is stable and reproduces true to type in successive generations of asexual reproduction.

The most similar known hosta cultivar known to the applicant is: Hosta ‘Déjà Blu’ (not patented). ‘Déjà Blu’ has a similar white bolting between the yellow margin and bluish green center. However, the new plant has a much larger leaf and larger habit, has less lavender in the flowers and blooms later that ‘Déjà Blu’. Hosta ‘Seducer’ differs from its female parent by having a stable variegated leaf margin compared to an unstable streaking throughout the leaf, more cordate leaf blades with less rugose and a taller flower scape with slightly more lavender buds.

Hosta ‘Seducer’ differs from all other hostas known to the applicant, by the combination of the following traits.

• • 1. Cordate leaf blades with yellowish green margin a bluish dark green center.
  • 2. Developing a thin creamy white bolt irregularly flashing and following the jetting between the margin and center colors.
  • 3. Lavender buds opening to near white flowers beginning in late June.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the 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.

DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2001 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. The new plant, Hosta ‘Seducer’, 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 three-year old plant in a 50% shaded trial garden in Zeeland, Mich. with supplemental water and fertilizer.
