Campanula plant named ‘Summertime Blues’

Abstract

A new and distinct Campanula plant with large bells of deep violet colored flowers, multiple inflorescences, no seed set, and long bloom time (from May through September in Canby, Oreg).

Description

Botanical Classification: Campanula spp. (C. punctata×C. trachelium).

Variety Denomination: ‘Summertime Blues’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Campanula plant that is given the cultivar name of ‘Summertine Blues’. Campanula is in the family Campanulaceae. Campanula ‘Summertime Blues’ originated from a planned cross between Campanula punctata ‘Bowl of Cherries’ (U.S. Plant Pat. No. 13,194), as the seed parent, and Campanula trachelium ‘Bernice’ (an unpatented plant), as the pollen parent. The offspring from the cross were planted out and this selection was made for its fine characteristics.

SUMMARY OF THE INVENTION

This new and unique Campanula hybrid is distinguished by:

• • 1. Large bells of deep violet colored flowers;
  • 2. Multiple inflorescences;
  • 3. No seed set; and
  • 4. Long bloom time (May through September in Canby, Oreg.).

This new cultivar has been reproduced only by asexual propagation (tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

COMPARISON TO SIMILAR CAMPANULA

Compared to its seed parent, Campanula punctata ‘Bowl of Cherries’ (U.S. Plant Pat. No. 13,194), Campanula ‘Summertime Blues’ has deep violet rather than deep red purple colored flowers. The new variety is taller and is not rhizomatous.

Compared to its pollen parent, Campanula trachelium ‘Bernice’, an unpatented plant, the new variety has a single rather than a double flower. They have similar flower color. Campanula trachelium ‘Bernice’ is leafier than the new variety.

Compared to Campanula ‘Mystic Bells’, an unpatented plant, the near variety has deeper violet corolla color.
