Botanical classification: Erysimum hybrid.
Variety denomination: ‘Cdcery3’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Erysimum of hybrid origin that is botanically known as Erysimum ‘Cdcery3’. ‘Cdcery3’ is a new cultivar of wallflower grown for use as an ornamental landscape plant.
The new cultivar derived from a controlled breeding program by the Inventor in Winchester, The United Kingdom. The goals of the breeding program are to create new cultivars of Erysimum that perform well in the garden, have large flowers with unique colors that do not fade easily, compact and well-branched plant habits, and dark green foliage.
The Inventor made crosses between 2011 and 2016 between unnamed and unpatented plants of Erysimum in the Inventor's breeding program as both the female and male parents. The seeds were pooled from the crosses and therefore the exact parents are unknown. ‘Cdcery3’ was selected as a single unique plant in 2018 from the resulting seedlings of the above crosses.
Asexual propagation of the new cultivar was first accomplished by stem cuttings in Winchester, The United Kingdom in 2017 by the Inventor in order to evaluate multiple plants. Asexual propagation by stem cuttings 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 are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Cdcery3’ as a unique cultivar of Erysimum.
- 1. ‘Cdcery3’ exhibits foliage that is silverly dark green in color.
- 2. ‘Cdcery3’ exhibits early flowering from spring into summer in The United Kingdom.
- 3. ‘Cdcery3’ exhibits flowers that are vibrant purple in color with minimal fading.
- 4. ‘Cdcery3’ exhibits flowers and leaves that are large in size.
- 5. ‘Cdcery3’ exhibits strong and upright stems.
- 6. ‘Cdcery3’ exhibits a low maintenance, well-branched, and compact plant habit.
- 7. ‘Cdcery3’ exhibits drought resistance and good winter hardiness in The United Kingdom.
‘Cdcery3’ can be most closely compared to the Erysimum cultivars ‘Cdcery1’, ‘Cdcery2’, and ‘Bowles's Mauve’ (not patented). ‘Cdcery1’ and ‘Cdcery2’ are both similar to ‘Cdcery3’ in having silvery dark green foliage, vibrant flowers with minimal fading, a low maintenance, well-branched, and compact plant habit, drought resistance and good winter hardiness. ‘Cdcery1’ differs from ‘Cdcery3’ in having flowers that are vivid red in color. ‘Cdcery2’ differs from ‘Cdcery3’ in having flowers that are warm orange in color. ‘Bowles's Mauve’ differs from ‘Cdcery3’ in having smaller flowers that are lighter purple in color that fades quickly and leaves that are smaller in size.

BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Erysimum. The photographs were taken of a 6-month-old plant of the new cultivar as grown in a greenhouse in 26-cm containers in Waddinxveen, The Netherlands.
The photograph in FIG. 1 provides a side view of ‘Cdcery3’ in bloom.
The photograph in FIG. 2 provides a close-up view of an inflorescence of ‘Cdcery3’.
The photograph in FIG. 3 provides a close-up view of the foliage of ‘Cdcery3’.
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 new Erysimum.
