Botanical Classification: Campanula hybrid.

Variety Denomination: ‘Pink Octopus’.

The present invention relates to a new and distinct cultivar of Campanula plant and given the cultivar name of ‘Pink Octopus’. Campanula is in the family Campanulaceae. Campanula ‘Pink Octopus’ is a F2 seedling of a cross between Campanula takesimana ‘Beautiful Trust’ (U.S. Plant Pat. No. PP12,815), as the seed parent, and Campanula punctata ‘Pink Chimes’ (U.S. Plant Pat. No. PP13,156), as the pollen parent.

This new and unique Campanula is distinguished by:

    • 1. Large, purple pink flowers, with lobes cut into linear segments, octopus-like.
    • 2. Deep green, glossy leaves with incised margins.
    • 3. Very low seed set resulting in longer bloom time.

This new cultivar has been reproduced only by asexual propagation (tissue culture). Each of the progeny exhibits identical characteristics of 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.


The photograph shows Campanula ‘Pink Octopus’ growing in a two gallon container in a sunny greenhouse in August in Canby, Oreg.


The following is a detailed description of the new Campanula based on observations of two year old specimen grown in a two gallon container outside in full sun under typical weathers in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95 degrees F. in August to 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart.
