plant named ‘B201’

Abstract

A new cultivar of Hosta named ‘B201’ that is characterized by its leaf petioles and flower stems that are dark red in color, its foliage that is glossy green in color with broad margins that emerge yellow and turn to creamy white in color, its leaves that are thick and strong, its vigorous growth habit and its high resistance to slugs.

Description

Botanical classification: Hosta hybrida.

Cultivar designation: ‘B201’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hosta, botanically of hybrid origin and known as a Hosta ‘B201’ and is hereinafter referred to by its cultivar name ‘B201’.

The new cultivar was discovered by the Inventor in June of 2011 as a naturally-occuring chimeral mutation of an unnamed Hosta plant from the Inventor's breeding program that was growing in a container outdoors in Barneveld, The Netherlands.

Asexual propagation of the new cultivar was first accomplished by division by the Inventor in Barneveld, The Netherlands in 2013. Asexual propagation of the new cultivar by division and tissue culture using meristematic tissue has shown that the unique features are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘B201’ as a new and unique cultivar of Hosta.

• • 1. ‘B201’ exhibits leaf petioles and flower stems that are dark red in color.
  • 2. ‘B201’ exhibits foliage that is glossy green in color with broad margins that emerge yellow and turn creamy white in color.
  • 3. ‘B201’ exhibits leaves that are thick and strong.
  • 4. ‘B201’ exhibits a vigorous growth habit.
  • 5. ‘B201’ exhibits high resistance to slugs.

The parent plant differs from ‘B201’ in having much thinner margins and leaves that are thinner with less substance. ‘B201’ can be most closely compared to the Hosta cultivar ‘Secret Treasure’ (U.S. Plant Pat. No. 22,789). ‘Secret Treasure’ is similar to ‘B201’ in leaf vareigation pattern and in having red stems. ‘Secret Treasure’ differs from ‘B201’ in having thinner leaves with less substance, thinner leaf margins, and a taller plant height.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs were taken of 2 year-old plants as grown outdoors in a 27-cm container in Barneveld, The Netherlands.

FIG. 1 provides an overall view of the plant of ‘B201’.

The photograph in FIG. 2 provides a close-up view of a leaf of ‘B201’.

FIG. 3 provides a close-up view of the leaf petioles of ‘B201’.

FIG. 4 provides a close-up view of an inflorescence of ‘B201’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Hosta.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 2 year-old plants as grown outdoors in a 17-cm container in Barneveld, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
