Hosta plant named ‘Magic Fire’

Abstract

A new and distinct cultivar of Hosta plant named ‘Magic Fire’, characterized by its relatively compact plant habit; green and pale yellow variegated leaf color; and light lavender-colored flowers that are positioned above the foliage on strong and erect scapes.

Description

Botanical designation: Hosta fluctuans.

Cultivar denomination: ‘Magic Fire’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta fluctuans, and hereinafter referred to by the cultivar name Magic Fire.

The new Hosta was discovered by the Inventor in a controlled environment in Barneveld, The Netherlands, as a whole plant mutation of the Hosta fluctuans cultivar Sagae, not patented, in June, 1998.

Asexual reproduction of the new cultivar by divisions and by tissue-cultured microplants in a controlled environment in Barneveld, The Netherlands since January, 2004, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Magic Fire have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Magic Fire’. These characteristics in combination distinguish ‘Magic Fire’ as a new and distinct Hosta cultivar:

• • 1. Relatively compact plant habit.
  • 2. Green and pale yellow variegated leaf color.
  • 3. Light lavender-colored flowers that are positioned above the foliage on strong scapes.

Plants of the new Hosta can be compared to plants of the parent, the cultivar Sagae. In side-by-side comparisons conducted in Barneveld, The Netherlands, plants of the new Hosta differed from plants of the cultivar Sagae in the following characteristics:

• • 1. Leaves of plants of the new Hosta were more cordate than leaves of plants of the cultivar Sagae.
  • 2. Leaves of plants of the new Hosta had broad pale yellow-colored margins whereas leaves of plants of the cultivar Sagae had very narrow pale yellow-colored margins.
  • 3. Leaves of plants of the new Hosta had eight vein pairs whereas leaves of plants of the cultivar Sagae had seven vein pairs.

Plants of the new Hosta can also be compared to plants of the cultivar Liberty, disclosed in U.S. Plant Pat. No. 12,531. In side-by-side comparisons conducted in Barneveld, The Netherlands, plants of the new Hosta differed from plants of the cultivar Liberty in the following characteristics:

• • 1. Leaves of plants of the new Hosta were much smaller than leaves of plants of the cultivar Liberty.
  • 2. Leaves of plants of the new Hosta had eight vein pairs whereas leaves of plants of the cultivar Liberty had twelve vein pairs.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hosta, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Hosta.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Magic Fire’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers and a typical leaf of ‘Magic Fire’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photographs and the following description were about two years old and grown in 17-cm containers in a glass-covered greenhouse and under conditions which closely approximate commercial production conditions during the spring in Barneveld, The Netherlands. During the production of the plants, day temperatures were about 20° C. and night temperatures were about 16° C.
