Abstract
A new cultivar of Vernonia plant named ‘Summer's End’ that is characterized by its bushy upright plant habit with stems that do not lodge, its tolerance to high pH (alkaline) soils, its foliage that is olive green in color with no red or purple tints when grown in full sun, its high resistance to rust and powdery mildew, its hardiness in U.S.D.A. Zones 4 to 8, and its drought tolerance.
Description
Botanical classification: Vernonia hybrid.
Variety denomination: ‘Summer's End’.
The present invention relates to a new and distinct cultivar of Vernonia plant of hybrid origin and will be referred to hereinafter by its cultivar name, ‘Summer's End’. The new cultivar represents a new herbaceous perennial grown for landscape use.
The new invention arose from an ongoing breeding program by the Inventor in Glencoe, Ill. The objectives of the breeding program are to develop improved cultivars of interspecific hybrids of Vernonia with novel ornamental traits such as plant morphologies (especially leaf and capitula size), reduced overall plant habits, improved disease resistance, hardiness in U.S.D.A. Zone 5 and in ground cultural adaptability.
‘Summer's End’ was derived from a cross made in September of 2012 under controlled conditions between Vernonia lettermannii ‘Iron Butterfly’ (not patented) as the female seed parent and an unnamed and unpatented plant of Vernonia larseniae as the male pollen parent. ‘Summer's End’ was selected in October of 2015 as a single unique plant amongst the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished by shoot tip cuttings by the Inventor in June of 2016 in Glencoe, Ill. Asexual propagation by shoot tip and subterminal cuttings has determined that the characteristics of this cultivar are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Summer's End’ as a new and unique cultivar of Vernonia.
-
- 1. ‘Summer's End’ exhibits a bushy upright plant habit with stems that do not lodge.
- 2. ‘Summer's End’ exhibits a tolerance to high pH (alkaline) soils.
- 3. ‘Summer's End’ exhibits foliage that is olive green in color with no red or purple tints when grown in full sun.
- 4. ‘Summer's End’ exhibits a high resistance to rust (Coleosporium sp.) and powdery mildew (Golovinomyces sp.).
- 5. ‘Summer's End’ exhibits hardiness in U.S.D.A. Zones 4 to 8.
- 6. ‘Summer's End’ exhibits drought tolerance.
The female parent, ‘Iron Butterfly’, differs from ‘Summer's End’ in having a plant size that is much shorter in height, about half the number of florets per capitulum, stems and foliage that is tinted red in color when exposure to full sun, and foliage that is finer. The male parent, an unnamed plant of Vernonia larseniae, differs from ‘Summer's End’ in having phyllaries that are silvery white in color, strongly adpressed to the capitula with blunt to slightly rounded tips, foliage that is silver-white and covered with very dense pubescence, many more florets per capitulum, and in not being reliably hardy in U.S.D.A. Zone 5. ‘Summer's End’ can also be compared to the Vernonia cultivars ‘Summer's Surrender’ (U.S. Plant Pat. No. 28,475) and ‘Summer's Swan Song’ (U.S. Plant Pat. No. 28,556). ‘Summer's Surrender’ and ‘Summer's Swan Song’ are both similar to ‘Summer's End’ in having many upright stems that do not lodge and in having high resistance to powdery mildew and rust. ‘Summer's Surrender’ differs from ‘Summer's End’ in having more florets per capitulum, a smaller plant height and width, foliage that is longer in length, and a shorter blooming period. ‘Summer's Swan Song’ differs from ‘Summer's End’ in having a shorter plant height when mature, foliage that becomes tinted red-purple in color in full sun, more florets per capitulum, and phyllaries that are strongly adpressed to the capitula and have blunt to slightly rounded tips.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Vernonia. The photographs were taken of ‘Summer's End’ as grown in a trial garden in Glencoe, Ill.
The photograph in FIG. 1 provides a side view of a five-year-old plant of ‘Summer's End’ in bloom.
The photograph in FIG. 2 provides a close-up view of the flowers of a five-year-old plant of ‘Summer's End’.
The photograph in FIG. 3 provides a view of a group of three-year-old plants of ‘Summer's End’.
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 Vernonia.
The following is a detailed description collected from two-year-old plants of the new cultivar as grown outdoors over summer in one-gallon containers, and from three to five-year-old plants grown in-ground in Glencoe, Ill. 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 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
