Salvia plant named ‘Eggben009’

Latin name of the genus and species: Salvia gregii×microphylla.

Variety denomination: ‘EGGBEN009’.

The new Salvia cultivar is a product of a planned breeding program conducted by the inventor, Howard Bentley, in Wonga Park, Victoria, Australia. The objective of the breeding program was to produce new Salvia varieties with denser plant habits, strong garden performance, in a range of flower colors. The controlled pollination resulting in this new variety was made during March and April of 2007.

The parent variety is Salvia gregii×microphylla ‘Eggben005’, U.S. Plant patent application Ser. No. 13/506,155. The parent variety was self-pollinated to produce an F2 generation of seed. This seed was collected, sown and grown outdoors under field conditions. The new variety was identified as a potentially interesting selection in October of 2009, at a research greenhouse in Wonga Park, Australia. Further observations and evaluations were made throughout 2010 and 2011.

Asexual reproduction of the new cultivar ‘EGGBEN009’ by vegetative cuttings was first performed during 2011, at a research greenhouse in Wonga Park, Australia. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.

The cultivar ‘EGGBEN009’ 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 ‘EGGBEN009’ These characteristics in combination distinguish ‘EGGBEN009’ as a new and distinct Salvia cultivar:

1. Bushy plant habit. 2. Bright pink flower color with white eye. 3. Sturdy inflorescence. 4. Dense plant habit. 5. Moderate anthocyanin coloration of calyx.

Plants of the new cultivar ‘EGGBEN009’ are similar to plants of the parent, in most horticultural characteristics, however, plants of the new cultivar ‘EGGBEN009’ produce a somewhat bright and darker colored flower than the parent variety. Additionally, the new variety typically produces foliage with more prominent venation and undulation.

Plants of the new cultivar can be compared to the commercial variety Salvia gregii ‘RFD-S018’, U.S. Plant Pat. No. 14,699. The two Salvia varieties are very similar in most horticultural characteristics, however, the new variety produces a flower with a white eye, and a stronger and longer peduncle. Foliage differs as well; the new variety has foliage white is more crenate to serrate than ‘RFD-S018’.

Plants of the new cultivar can be compared to the commercial variety Salvia gregii ‘James Compton’, unpatented. The two Salvia varieties are very similar in most horticultural characteristics, however, the new variety produces an inflorescence with more flowers. Foliage differs as well; the new variety has foliage white is more crenate to serrate than ‘James Compton’.

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘EGGBEN009’.

The plant was grown outdoors, in Wonga Park, Australia. Age of the plant photographed is approximately 50 weeks from an unrooted cutting. 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.
