Description

Latin name of the genus and species: Campanula hybrid.

Variety denomination: ‘USCAMP10’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a result of a planned breeding program directed by the inventor, Ushio Sakazaki, a citizen of Japan. The seed parent is the unpatented Campanula hybrid ‘Kent Belle’ and the pollen parent is the unpatented variety Campanula punctata ‘Kurokawae’. The cross resulting in ‘USCAMP10’ was made Jun. 20, 2003. The new variety was discovered Sep. 20, 2004, by the inventor in a non-commercial nursery in Hikone, Japan.

Asexual reproduction of the new cultivar ‘USCAMP10’ by vegetative division was first performed Oct. 14, 2004 at a non-commercial nursery in Hikone, Japan. Multiple generations have since been produced and have shown that the unique features of this cultivar are stable and reproduced true to type in successive generations. The new cultivar was first sold and made available to the public in April 2011.

SUMMARY OF THE INVENTION

The cultivar ‘USCAMP10’ 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 ‘USCAMP10’ These characteristics in combination distinguish ‘USCAMP10’ as a new and distinct Campanula cultivar:

    • 1. Vigorous and compact growth habit.
    • 2. Large flowers.
    • 3. Dark Violet-blue flowers.
    • 4. Longer flowering period.

PARENT COMPARISON

Plants of the new cultivar ‘USCAMP10’ are similar to plants of the seed parent, Campanula hybid ‘Kent Belle’, in most horticultural characteristics, however, plants of the new cultivar ‘USCAMP10’ produce more branches than the seed parent. Plants of ‘USCAMP10’ are overall shorter than the seed parent, and produce longer flowers.

Plants of the new cultivar ‘USCAMP10’ are similar to plants of the pollen parent Campanula punctata ‘Kurokawae’ in most horticultural characteristics, however, plants of the new cultivar ‘USCAMP10’ are overall taller than the pollen parent. Flower color of the new variety is dark blue, whereas the pollen parent has light pink flower. Additionally, the new variety has grows more vigorously than the pollen parent.

COMMERCIAL COMPARISON

‘USCAMP10’ can be compared to the commercial variety Campanula ‘Get Mee’®, unpatented. The two varieties are similar in most horticultural characteristics, however, plants of ‘USCAMP10’ produce larger flowers, of a darker blue. Additionally, plants of the new variety produce a different shaped foliage than the comparator.

‘USCAMP10’ can be compared to the commercial variety Campanula carpatica ‘Clips Blue’®, unpatented. The two varieties are similar in most horticultural characteristics, however, plants of ‘USCAMP10’ produce flowers that are both narrower and longer. Additionally the flower color of ‘USCAMP10’ is darker.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a of typical plant of ‘USCAMP10’ grown in a poly house, in Bonsall, Calif., in a commercial 6 inch container. The photographs was 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.
