ABSTRACT:
Botanical classification:
Brunnera Macrophylla.
Variety denomination: ‘Silver Wings’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Siberian Bugloss that is a fast growing perennial with a clumping habit, grown for use in borders or as an accent plant. The new cultivar is known botanically as a
Brunnera macrophylla
and will be referred to hereinafter by the cultivar name ‘Silver Wings’.
‘Silver Wings’ was discovered by the inventors in 1997 in a cultivated area of Chimacum, Wash. as a sport in a flat of tissue cultured
Brunnera macrophylla
‘Langtrees’ (unpatented). The distinguishing characteristics of ‘Silver Wings’ are the thin cream-white margin on the leaves, the silver overlay on the surface of the leaves, and the leaves resistance to burning. The closest comparison plants are
Brunnera macrophylla
‘Variegata’ (unpatented) and the parent
Brunnera macrophylla
‘Langtrees’. ‘Silver Wings’ is distinguishable from ‘Langtrees’ by the silver overlay on the surface of the leaves. ‘Silver Wings’ is unique from ‘Variegata’ because unlike ‘Variegata’, its leaves are resistant to burning. When planted in partial shade and moist soil ‘Silver Wings’ maintains a clean and vigorous appearance all season.
‘Silver Wings’ was first asexually propagated by the inventors in 1998 in Chimacum, Wash. by division. Since that time, under careful observation, the distinguishing characteristics have been determined stable and uniform in successive generations.
SUMMARY OF THE INVENTION
The following represent the distinguishing characteristics of the new Brunnera cultivar ‘Silver Wings’. In combination these traits set ‘Silver Wings’ apart from all other existing varieties of Brunnera known to the inventor. ‘Silver Wings’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
1. Brunnera ‘Silver Wings’ exhibits variegated foliage that is gray-green with a silver overlay on the surface of the leaves and thin cream-white margins.
2. Brunnera ‘Silver Wings’ is a small to medium size perennial grown for use in borders or as an accent plant.
3. Brunnera ‘Silver Wings’ is a prolific bloomer producing clusters of tiny violet-blue flowers in mid to late spring.
4. Brunnera ‘Silver Wings’ grows to 60 cm. in height and 60 cm. in width at maturity.
5. The foliage of Brunnera ‘Silver Wings’ is resistant to burning.
6. Brunnera ‘Silver Wings’ exhibits a clumping habit.
