Abstract

A new cultivar of Epimedium plant, ‘Magnificent’, that is characterized by its ge similar to plants of the species Epimedium pinnatum, its flowers that are conspicuously carried above the foliage, its unique flower coloration with spurred petals that are shorter than the sepals and orange-brown in color and sepals that are pale yellow in color, its flowers that are large in size, its foliage that is dark in color in the winter, its spreading plant shape, and its young leaves that are red-purple in color and change to deep yellow-green as they mature.

Description

Botanical classification: Epimedium hybrid.

Cultivar designation: ‘Magnificent’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Epimedium plant of hybrid origin, botanically known as Epimedium ‘Magnificent’ and will be referred to hereafter by its cultivar name, ‘Magnificent’.

‘Magnificent’ originated as a seedling that arose from seed planted from open pollination of an unnamed plant of E. pinnatum subsp. colchicum by the Inventor in Hantay, France in March of 2011. ‘Magnificent’ was selected as a single unique plant from the resulting seedlings in spring of 2012.

Asexual propagation of the new cultivar was first accomplished by rhizome division in Hantay, France in September of 2015 by the Inventor. Asexual propagation by rhizome division has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

- 1. ‘Magnificent’ exhibits foliage similar to plants of the species Epimedium pinnatum.
- 2. ‘Magnificent’ exhibits flowers that are conspicuously carried above the foliage.
- 3. ‘Magnificent’ exhibits a unique flower coloration with spurred petals that are shorter than the sepals and orange-brown in color and sepals that are pale yellow in color.
- 4. ‘Magnificent’ exhibits flowers that are large in size.
- 5. ‘Magnificent’ exhibits foliage that is dark in color in the winter.
- 6. ‘Magnificent’ exhibits a spreading plant shape.
- 7. ‘Magnificent’ exhibits young leaves that are red-purple in color and change to deep yellow-green in color as they mature.

The female parent of ‘Magnificent’ differs from ‘Magnificent’ in having flowers that are deep yellow in color and mature foliage that is lighter yellow-green in color. ‘Magnificent’ can be compared to the Epimedium cultivars ‘Amber Queen’ (U.S. Plant Pat. No. 17,197) and ‘Fröhnleiten’ (not patented). ‘Amber Queen’ is similar to ‘Magnificent’ in general flower coloration. ‘Amber Queen’ differs from ‘Magnificent’ in having spurred petals that are much longer than the sepals and light yellow in color, sepals that are pale orange in color, and in lacking dark foliage color in winter. ‘Fröhnleiten’ is similar to ‘Magnificent’ in winter foliage color. ‘Fröhnleiten’ differs from ‘Magnificent’ in having spurred petals that are much shorter and lighter orange-brown in color and in having darker yellow sepals.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant less than one year prior to the effective filing date would have been obtained from a direct or indirect disclosure from the Inventor under 35 U.S.C. 102(b)(1).

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Epimedium. The photographs were taken of a 2.5-year-old plant of ‘Magnificent’ as field grown in Hantay, France and place in a 33-cm container for the photographs.

The photograph in FIG. 1 provides a side view of ‘Magnificent’ in bloom.

The photograph in FIG. 2 provides a view of an inflorescence of ‘Magnificent’.

The photograph in FIG. 3 provides a close-up view of the flowers of ‘Magnificent’.

The photograph in FIG. 4 provides a close-up view of the mature foliage of ‘Magnificent’.

The photograph in FIG. 5 provides a close-up view of the young foliage of ‘Magnificent’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the colors of the new Epimedium.
