Abstract
A new cultivar of Magnolia named ‘Stellar Ruby’ that is characterized by its a very narrow and dense pyramidal growth habit, its floriferous blooming habit, its flowers that are purple in color and fragrant, its fast plant growth habit, its cold hardiness at least to U.S.D.A. Zone 7, and its ability to bloom on plants that are young in age.
Description
Botanical classification: Magnolia figo.
Variety denomination: ‘Stellar Ruby’.
The present invention relates to a new and distinct cultivar of Magnolia figo. The new cultivar will be referred to hereafter by its cultivar name, ‘Stellar Ruby’. ‘Stellar Ruby’ is a new cultivar of Magnolia grown for use as a landscape shrub.
The new cultivar of Magnolia is a selection from a controlled breeding program conducted by the Inventor in Zebulon, N.C. The objectives of the breeding program were to create a new Magnolia cultivar with fragrant purple flowers with good cold hardiness and evergreen foliage.
‘Stellar Ruby’ originated from a cross made in 2004 between an unnamed and unpatented plant of Magnolia figo var. crassipes as the female parent and an unnamed and unpatented plant of Magnolia figo var. skinneriana as the male parent. ‘Stellar Ruby’ was selected as a single unique plant in 2010 from amongst the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings by the Inventor in Zebulon, N.C. in late spring of 2014. Asexual propagation by semi-hardwood stem cuttings has determined that the characteristics of the new cultivar are stable and are 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 ‘Stellar Ruby’ as a new and unique cultivar of Magnolia.
- 1. ‘Stellar Ruby’ exhibits a very narrow and dense pyramidal growth habit.
- 2. ‘Stellar Ruby’ exhibits a floriferous blooming habit.
- 3. ‘Stellar Ruby’ exhibits flowers that are purple in color and fragrant.
- 4. ‘Stellar Ruby’ exhibits a fast plant growth habit.
- 5. ‘Stellar Ruby’ exhibits very dark green foliage.
- 6. ‘Stellar Ruby’ exhibits cold hardiness at least to U.S.D.A. Zone 7.
- 7. ‘Stellar Ruby’ exhibits blooms on plants that are young in age.
The female parent of ‘Stellar Ruby’ differs from ‘Stellar Ruby’ in having flowers that are white in color, a spreading non pyramidal growth habit, flowers that have no fragrance and leaves that are pale green in color. The pollen parent of ‘Stellar Ruby’ differs from ‘Stellar Ruby’ in being less cold hardy and in having a low sprawling plant habit, flowers that are lighter purple in color and a less floriferous blooming habit. ‘Stellar Ruby’ can be most closely compared to the Magnolia figo var. crassipes cultivar ‘Purple Queen’ (not patented). ‘Purple Queen’ is similar to ‘Stellar Ruby’ in having flowers that are purple in color. ‘Purple Queen’ differs from ‘Stellar Ruby’ in being less cold hardy and in having flowers that are darker purple in color, a less floriferous blooming habit and a much more open growth habit.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Magnolia. The photographs were taken of a 2 year-old plant (from a cutting) as grown outdoors in a five-gallon container in Zebulon, N.C.
The photograph in FIG. 1 provides a side view of the plant habit of ‘Stellar Ruby’.
The photograph in FIG. 2 provides a close-up view of a flower of ‘Stellar Ruby’.
The photograph in FIG. 3 provides a close-up view of the flower buds of ‘Stellar Ruby’.
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 Magnolia.
The following is a detailed description of 2 year-old plants of the new cultivar as grown outdoors in five-gallon containers in Zebulon, N.C. 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.
