Abstract

A new cultivar of Erysimum named ‘Walfrasun’ that is characterized by a large compact, bushy habit, silver-green leaves, chocolate-purple buds and deep-yellow flowers that are strongly sweet in fragrance. In combination these traits set ‘Walfrasun’ apart from all other existing varieties of Erysimum known to the inventor.

Description

BOTANICAL CLASSIFICATION
Erysimum cultivar Walfrasun.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of perennial wall flower that is grown as an ornamental for its compact, bushy habit and fragrant yellow flower spikes that increase in height as the plant matures. The new cultivar is known botanically as Erysimum and will be referred to hereinafter by the cultivar name ‘Walfrasun’.
‘Walfrasun’ originated in a cultivated area of West Sussex, England. In 1993 a few seeds were produced on an open pollinated plant of Erysimum ‘Bredon’ (not patented). These seeds were sown by the inventor. One seed germinated, producing a seedling that flowered in 1994. The inventor observed the seedling during a number of months in 1994 and selected it in the same year as ‘Walfrasun’.
‘Walfrasun’ does not set seed and is presumed to be sterile. In addition to being sterile, ‘Walfrasun’was selected for its large dimensions, large deep-yellow flowers, strong, sweet scented flowers and buds that are chocolate-purple in color. ‘Walfrasun’ is a perennial suitable for planting in full sun or partial shade. ‘Walfrasun’ is closest in comparison to Erysimum ‘Bredon’ and is distinguishable from ‘Bredon’ primarily by its vigor, its more silver foliage, its larger mature flower spikes, its deeper chocolate-purple buds, its large deep-yellow flowers that exhibit a strong and sweet fragrance and its absence of seed.
The first asexual reproduction of ‘Walfrasun’ was conducted by the inventor in 1995 in a cultivated area of West Sussex, England. The method used for asexual propagation was vegetative cuttings. The characteristics of the new cultivar have been determined 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 the new cultivar. These traits in combination distinguish ‘Walfrasun’ from all other commercial varieties known to the inventor. ‘Walfrasun’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in enviromental, climatic and cultural conditions.
1. Erysimum ‘Walfrasun’ exhibits a compact bushy habit.
2. Erysimum ‘Walfrasun’ exhibits leaves with a silver sheen.
3. Erysimum ‘Walfrasun’ exhibits large deep-yellow flower spikes that increase in height as the plant matures.
4. Erysimum ‘Walfrasun’ exhibits strong, sweet scented flowers.
5. Erysimum ‘Walfrasun’ exhibits buds that are chocolate-purple in color.
6. Erysimum ‘Walfrasun’ does not set seed and is presumed to be sterile.
7. Erysimum ‘Walfrasun’ is 40-50 cm. in height and 40-60 cm. in width at maturity.
8. Erysimum ‘Walfrasun’ is hardy to USDA Zones 7-10.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying drawings illustate the distinguishing traits of the new Erysimum cultivar named ‘Walfrasun’.
The first drawing illustrates an entire plant from a side perspective.
The second drawing shows a close-up view of the flowers.
The first and second drawings show plants grown in three-gallon containers out-of-doors in May in Sussex, England.
The third and fourth drawings show comparisons of ‘Walfrasun’with its parent ‘Bredon’ in Sussex, England.
The third drawing shows a 4-month old plant of each variety in October, illustrating the more silver foliage and greater vigor of ‘Walfrasun’.
The fourth drawing shows 12-month old plants of each variety in September, illustrating a typical flower spike of each variety at the end of the flowering period to illustrate the longer spikes of ‘Walfrasun’ and its wider spacing between the spent flower positions. All drawings were made using conventional photographic techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of ‘Walfrasun’ as grown in three-gallon containers out-of-doors for 2.5 years in Sussex, England. The color determinations are in accordance with The R.H.S.
