Botanical classification: Rosa hybrida.
Variety denomination: ‘VLR13003’.
CROSS REFERENCE TO A RELATED APPLICATION
This application claims priority to a Canadian Plant Breeder's Rights Application No. 22-11140 filed on Dec. 06, 2022, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The Applicant received the information for the Plant breeders' rights application indirectly from the Inventors.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Rosa of hybrid origin. The new cultivar will be referred to hereafter by its cultivar name, ‘VLR13003’. ‘VLR13003’ is a new cultivar of hybrid rose grown for use as a container and landscape plant.
The new cultivar was derived from a breeding program by the Inventors in Vineland Station, Ontario, Canada. The goal of the breeding was to produce a new cultivar of rose with a cold hardiness to U.S.D.A. Zone 4 and resistance to black spot disease. The Inventor made a cross in 2013 between ‘Candelabra’ (not patented) as the female and a non-patented plant from the Inventor's breeding program designated as No. 333 as the male parent. ‘VLR13003’ was selected in 2015 as a single unique plant amongst the resulting seedlings that resulted from the above crosses.
Asexual propagation of the new cultivar was first accomplished by stem cuttings by the Inventors in September of 2015 in Vineland Station, Ontario, Canada. Asexual propagation by stem cuttings has determined that the characteristics of this cultivar are stable and 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 attributes in combination distinguish ‘VLR13003’ as a unique cultivar of Rosa.
- 1. ‘VLR13003’ exhibits flowers that are red in color.
- 2. ‘VLR13003’ exhibits flowers that are medium to large in size.
- 3. ‘VLR13003’ exhibits semi-double to double flowers.
- 4. ‘VLR13003’ exhibits flowers with a subtle fragrance.
- 5. ‘VLR13003’ exhibits an upright, bushy plant habit.
- 6. ‘VLR13003’ exhibits foliage that is semi glossy and dark green in color.
- 7. ‘VLR13003’ exhibits good resistance to black spot disease.
- 8. ‘VLR13003’ exhibits cold hardiness at least to U.S.D.A. Zone 4.
The female parent of ‘VLR13003’ differs from ‘VLR13003’ in having flowers that are smaller in size and lack fragrance and leaves that are glossy and small in size. The male parent of ‘VLR13003’ differs from ‘VLR13003’ in having flowers that are double, medium in size, and light yellow in color and leaves that are glossy. ‘VLR13003’ can be compared to the Rosa cultivar ‘Nicolas’ (not patented). ‘Nicolas’ differs from ‘VLR13003’ in having leaves that are dull and medium green in color, flowers that are slightly smaller and less fragrant, a shorter plant height, and less resistance to black spot disease.
