Latin name of the genus and species: Juniperus virginiana.
Variety denomination: ‘FARROWJVBF’.
BACKGROUND OF THE INVENTION
The new cultivar is a product of an open-pollination breeding program by the inventor, Michael W. Farrow. The open pollination resulting in ‘FARROWJVBF’ was made during 2009 at a commercial nursery in Warwick, Md. Selection of the new variety was made during 2010 at the same nursery. The seed parent of ‘FARROWJVBF’ is an unnamed, unpatented Juniperus virginiana. The pollen parent is unidentified.
After identifying the new variety as a potentially interesting selection, first propagation of ‘FARROWJVBF’ occurred by softwood cuttings at a commercial nursery in Warwick, Md. in 2010. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Five generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTION
The cultivar ‘FARROWJVBF’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘FARROWJVBF’ These characteristics in combination distinguish ‘FARROWJVBF’ as a new and distinct Juniperus cultivar:
- 1. Blue foliage.
- 2. Dense plant with a pyramidal shape.
- 3. Abundant small blue fruit.
COMMERCIAL COMPARISON
‘FARROWJVBF’ can be compared to the known commercial variety Juniperus virginiana ‘Burkii’, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘FARROWJVBF’ differ in the following ways:
- 1. New cultivar produces blue foliage, foliage of this comparator is more silver/gray.
- 2. Plants of the new variety are narrower than plants of this comparator.
- 3. Fruit of the new variety is blue; fruit of this comparator is gray.
PARENTAL COMPARISON
‘FARROWJVBF’ is similar to the seed parent in most horticultural characteristics, however, plants of ‘FARROWJVBF’ differ in the following:
- 1. The new cultivar has blue foliage; the seed parent has green foliage.
- 2. The new variety produces blue fruit; the seed parent produces green to blue fruit.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘FARROWJVBF’ grown outdoors in Grand Haven, Mich. The plant in FIG. 1 is approximately 5 years old, and exhibit the characteristic dense and pyramidal growth.
FIG. 2 illustrates a close-up view of the foliage and fruits.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
