Abstract
A new cultivar of Spiraea named ‘Matgold’ that is characterized by compact plant habit, its leaves that are copper red in color when young, changing to lemon gold in summer and changing to copper red in fall, and its flowers that open reddish pink in color and change to pink.
Description
Botanical classification: Spiraea hybrid.
Variety denomination: ‘Matgold’.
This application is related to a Canadian plant breeders' rights application filed on Jul. 27, 2015, application No. 15-8700. There have been no offers for sale anywhere in the world more than one year prior to the filing of this Application and no accessibility to one of ordinary skill in the art could have been derived from the printed plant breeder's rights documents.
The present invention relates to a new and distinct cultivar of Spiraea of hybrid origin will be referred to hereafter by its cultivar name, ‘Matgold’. ‘Matgold’ is a new variety of Spiraea grown for landscape use.
The new cultivar is the result of a controlled breeding program conducted by the Inventor in Angers, France with the goal of developing a new cultivar of Spiraea that exhibits young foliage that is copper red in color combined with deep pink-red flowers.
The new cultivar arose from a cross made by the Inventor in Angers, France in July of 2009 between Spiraea japonica ‘Bailcarol’ (not patented), as the female parent and Spiraea×bumalda ‘Denistar’ (U.S. Plant Pat. No. 22,432) as the male parent. The Inventor selected ‘Matgold’ as a single unique plant amongst the seedlings that resulted from the above cross in July of 2012.
Asexual propagation of the new cultivar was first accomplished by the Inventor by softwood stem cuttings in July of 2012 in Angers, France. Asexual propagation of the new cultivar by softwood 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, which in combination distinguish ‘Matgold’ as a new and unique cultivar of Spiraea.
-
- 1. ‘Matgold’ exhibits a compact plant habit.
- 2. ‘Matgold’ exhibits leaves that are copper red in color when young, changing to lemon gold in summer and changing to copper red in fall.
- 3. ‘Matgold’ exhibits flowers that open reddish pink in color and change to pink.
The female parent of ‘Matgold’, ‘Bailcarol’ is similar to ‘Matgold’ in having a round plant habit and leaves that are small in size. ‘Bailcarol’ differs from ‘Matgold’ in having young leaves that are yellow in color and flowers that are light pink (without red) in color. The male parent of ‘Matgold’, ‘Denistar’, differs from ‘Matgold’ in having a more upright plant habit, leaves that are larger in size and emerge red then change to dark green in color and in having flowers that bloom red then turn reddish pink in color. ‘Matgold’ can also be most closely compared to the Spiraea japonica cultivar ‘Goldflame’ (not patented). ‘Goldflame’ is similar to ‘Matgold’ in having copper colored young foliage. ‘Goldflame’ differs from ‘Matgold’ in having a less compact plant habit and in having young foliage that is lighter red in color.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Spiraea. The photographs were taken of a plant two years in age as grown outdoors in a two-gallon container in St. Thomas, Ontario, Canada.
The photograph in FIG. 1 provides a view of the overall plant habit of ‘Matgold’ in bloom.
The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Matgold’.
The photograph in FIG. 3 provides a close-up view of the young foliage of ‘Matgold’.
The photograph in FIG. 4 provides a view of the fall color.
The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Spiraea.
The following is a detailed description of two year-old plants of the new cultivar as grown outdoors in two-gallon containers in St. Thomas, Ontario, Canada. 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 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
